The χ2 test is not the oldest statistical test still in use. While it is an important and widely used statistical test, it is not the oldest. The χ2 test, also known as the chi-squared test, was developed by Karl Pearson in the late 19th century. It is used to determine whether there is a significant association between two categorical variables.

The χ2 test is a statistical test used to analyze categorical data. It is based on the principle of comparing observed frequencies in a contingency table to the expected frequencies. The test evaluates whether there is a significant association between two categorical variables or if any observed deviations are due to chance.

The χ2 test is commonly used in various fields such as biology, social sciences, market research, and quality control. It can be applied to analyze survey responses, compare proportions between groups, examine the relationship between variables, and assess the goodness of fit of a theoretical distribution to observed data.

However, the claim that the χ2 test is the oldest statistical test still in use is not accurate. There are several other statistical tests that predate the χ2 test, such as the t-test, developed by William Sealy Gosset (aka "Student") in the early 20th century, and the correlation coefficient, developed by Francis Galton in the late 19th century. These tests and others have been instrumental in the development of statistics and continue to be widely used today alongside the χ2 tes.

The following data shows the daily production of cell phones. 7, 10, 12, 15, 18, 19, 20. Mean The formula for finding the mean is: mean = (sum of observations) / (number of observations).

Therefore, the mean for the daily production of cell phones is: Mean = (7+10+12+15+18+19+20) / 7

= 101 / 7

Mean = 14.43

Variance The formula for finding the variance is: Variance = (sum of the squares of the deviations) / (number of observations - 1) Where the deviation of each observation from the mean is: deviation = observation - mean First, calculate the deviation for each observation:7 - 14.43

= -7.4310 - 14.43

Answer: To find the remainder when the polynomial 5x^2 + 10x - 15 is divided by x + 5, we can use polynomial long division or synthetic division. Here, we will use synthetic division:

The divisor is x + 5, so we change its sign and write -5 as the constant in the synthetic division setup. Then we list the coefficients of the terms of the dividend polynomial, in decreasing order of powers of x, and place a placeholder for the missing x term:

-5 | 5 0 10 -15

| -25 125 -675

+----------------

5 -25 135 -690

The remainder is the last number in the bottom row, which is -690. Therefore, the remainder when 5x^2 + 10x - 15 is divided by x + 5 is -690.

The correct symbol used for a column alias containing spaces is C. " " (quotation marks).

In SQL, when we want to assign a column alias containing spaces, we enclose the alias within double quotation marks. This is done to differentiate the alias from other SQL keywords or to handle cases where the alias includes special characters, spaces, or is case-sensitive.

For example, consider the following SQL query:

SELECT column_name AS "Column Alias"

FROM table_name;

In this query, we are selecting a column named "column_name" from the table "table_name" and assigning it the alias "Column Alias" containing spaces. By enclosing the alias within double quotation marks, we indicate to the database that it should treat the entire string as a single identifier or alias.

Using other symbols such as '', ||, or // will not achieve the desired result of creating an alias with spaces. These symbols have different meanings in SQL.

'' (two single quotation marks) typically represents an empty string or a string literal in SQL.

|| (double vertical bars) is the concatenation operator in some SQL dialects, used to combine strings or values.

// (double forward slashes) is commonly used for comments in various programming languages and does not have any special meaning for column aliases in SQL.

We will prove the statement  \(n^n / 3^n < n!\)for n ≥ 6 by induction. The base case is n = 6, and we will assume the inequality holds for some k ≥ 6. Using the induction hypothesis, we will show that it also holds for k + 1. Thus, proving the statement for n ≥ 6.

Base case: For n = 6, we have 6⁶ / 3⁶ = 46656 / 729 ≈ 64. As 6! = 720, we can see that the statement holds for n = 6.

Inductive step: Assume that the inequality holds for some k ≥ 6, i.e.,

\(k^k / 3^k < k!.\) We need to show that it holds for k + 1 as well.

Starting with the left side of the inequality:

\((k + 1)^{k + 1} / 3^{k + 1} = (k + 1) * (k + 1)^k / 3 * 3^k\)

\(= (k + 1) * (k^k / 3^k) * (k + 1) / 3\)

Since k ≥ 6, we know that (k + 1) / 3 < 1. Therefore, we can write:

\((k + 1) * (k^k / 3^k) * (k + 1) / 3 < (k + 1) * (k^k / 3^k) * 1\)

\(= (k + 1) * (k^k / 3^k)\)

< (k + 1) * k!

= (k + 1)!

Thus, we have shown that if the inequality holds for k, then it also holds for k + 1. By the principle of mathematical induction, the statement

\(n^n / 3^n < n!\) is proven for all n ≥ 6.

Step-by-step explanation:

The equation of a circle having endpoints of diameter as (4,9) and (4,-3) is (x - 4)² + (y - 3)² = 36.

The "center" of circle is called as midpoint of diameter.

The "x-coordinate" of "mid-point" is = (4+4)/2 = 4, and

The "y-coordinate" of "mid-point" is = (9+(-3))/2 = 3.

So, center of circle is (4,3),

The radius of circle is half the length of the diameter, which is distance between two endpoints of diameter. We find distance using distance formula:

⇒ distance = √((x₂ - x₁)² + (y₂ - y₁)²), where (x₁,y₁) and (x₂,y₂) are "end-points" of diameter.

⇒ distance = √((4 - 4)² + (9 - (-3))²)

⇒ √(144) = 12.

So, radius is 6.

The equation of circle with center (h,k) and radius "r" is : ⇒ (x - h)² + (y - k)² = r²,

Substituting the values

We get,

⇒ (x - 4)² + (y - 3)² = 6²,

⇒ (x - 4)² + (y - 3)² = 36,

Therefore, the equation of the circle is (x - 4)² + (y - 3)² = 36.

The probability of obtaining a value between two points will always be a positive value between 0 and 1.

If the measurements of a quantity are governed by the Gaussian distribution function (also known as the normal distribution), we can calculate the probability of obtaining a value between two specified points using the cumulative distribution function (CDF) of the normal distribution.

The CDF of the Gaussian distribution represents the probability that a random variable takes on a value less than or equal to a given point. To find the probability of obtaining a value between two points, we can subtract the CDF values corresponding to the lower and upper bounds.

Mathematically, the probability of obtaining a value between a lower bound (let's call it 'a') and an upper bound (let's call it 'b') can be calculated as follow

P(a < x < b) = Φ(b) - Φ(a)

Here, Φ represents the CDF of the Gaussian distribution.

To calculate this probability, we need to know the mean (μ) and standard deviation (σ) of the Gaussian distribution. These parameters define the shape and characteristics of the distribution.

Given the mean (μ) and standard deviation (σ), we can use statistical software, tables, or programming languages to find the values of Φ(b) and Φ(a) and then subtract them to obtain the probability.

It's important to note that the Gaussian distribution is symmetric, and the total area under the curve is equal to 1.

Jack's birthday is in 56 days.

The jumps end at point 56 on the number line.

Step-by-step explanation:

Since one week has 7 days.

So, 8 week = 8 x 7 =56 days.

Hence, Jack's birthday is in 56 days.

On the number line, the current time is being represented by 0.

When I take one jump from 0, I will reach the point 1 on the number line, which corresponds to 1 day.

Again, in my 2nd jump from point 1 on the number line, the next point on the number line will be 2 which corresponds to 2 days.

This process repeats until I complete the 56 jumps to get point 56 on the number line, which corresponds to 56 days.

In this way, the number line can be used to solve.

Hence, the jumps end at point 56 on the number line.

The probability that the flip results in a head is given as Pr[H] = 23. Therefore, the probability that the flip results in a tail is Pr[T] = 1 - Pr[H] = 1 - 23 = 13.

Let A be the event that a white marble is selected. We need to find the conditional probability Pr[H|A], i.e., the probability that the flip resulted in a head given that a white marble was selected.

Using Bayes' theorem, we have:

Pr[H|A] = (Pr[A|H]*Pr[H]) / Pr[A]

Pr[A|H] is the probability of selecting a white marble given that the flip resulted in a head. This is given by (9/25), since there are 9 white marbles out of 25 in the first urn.

Pr[A] is the total probability of selecting a white marble, which can be found using the law of total probability:

Pr[A] = Pr[A|H]*Pr[H] + Pr[A|T]*Pr[T]

= (9/25)*0.23 + (1/11)*0.13

= 0.0888 + 0.0118

= 0.1006

Pr[A|T] is the probability of selecting a white marble given that the flip resulted in a tail. This is given by (1/11), since there is only 1 white marble out of 11 in the second urn.

Therefore,

Pr[H|A] = (9/25 * 0.23) / 0.1006 = 0.6508

Hence, the probability that the flip resulted in a head given that a white marble was selected is 0.6508 (or approximately 0.65).
