8) A normally distributed set of population scores has a mean of 65 and a standard deviation of 10.2. The mean, of the sampling distribution of the mean, for samples of size 48 equals _________.
9) For the population and sample size given in question 8, the standard error of the mean equals _________.

Answers

The mean of a sampling distribution  

For samples of size 48, the mean of the sampling distribution of the mean is 65 and the standard error of the mean is approximately 1.477.

As given, A normally distributed set of population scores has a mean of 65 and a standard deviation of 10.2. Therefore, μ = 65 and σ = 10.2For samples of size n = 48, the mean of the sampling distribution of the mean will be the same as the population mean: μ_M = μ = 65 Hence, the mean of the sampling distribution of the mean is 65.

9) For the population and sample size given in question 8, the standard error of the mean can be calculated using the formula: SEM = σ/√where σ = standard deviation of the population = sample size Substituting the values in the formula, we get: SEM = 10.2/√48 ≈ 1.477Hence, the standard error of the mean is approximately 1.477.

Answer: For samples of size 48, the mean of the sampling distribution of the mean is 65 and the standard error of the mean is approximately 1.477.

what the metric system of measurement is based on the number?

Answers

The metric system of measurement is based on the number 10.

This system is also known as the International System of Units (SI) and is used in most countries around the world. In the metric system, various units of measurement are defined as multiples or fractions of a base unit, which is defined for each quantity being measured. For example, the base unit for length is the meter, and the base unit for mass is the kilogram. Prefixes such as kilo-, centi-, and milli- are used to indicate multiples or fractions of the base unit, based on factors of 10. For example, a kilometer is 1000 meters, a centimeter is 1/100 of a meter, and a milligram is 1/1000 of a gram. This makes the metric system easy to use and convert between units, as well as consistent and universally recognized.

1. An equation and the first step in its solution are shown.


Equation: x2 + 3x - 9 = 0


Step 1: x2 + 3x + h = 9+ h


What value of his used to solve the equation by the method of completing the square?

Answers

The value of h used to solve the equation by completing the square is 2.25.

To solve the equation x^2 + 3x - 9 = 0 using the method of completing the square, we add a constant term (h) to both sides of the equation to create a perfect square trinomial on the left side. The value of h that is used in this step depends on the coefficient of the x term (3).

To determine the value of h, we take half of the coefficient of the x term, square it, and add it to both sides of the equation. In this case, the coefficient of the x term is 3, so:

Step 1: x^2 + 3x + h = 9 + h

To find the value of h, we take half of 3, which is 3/2 or 1.5. We square 1.5 to get 2.25. So, the value of h used to solve the equation by completing the square is 2.25.

Please note that this is the value used in the specific step mentioned, and further steps may be required to complete the solution of the equation.

he expected to have 15 customers each day. to answer whether the number of customers follows a uniform distribution, a chi-square test for goodness of fit should be performed. (alpha

Answers

To determine whether the number of customers, which is expected to be 15 each day, follows a uniform distribution, a chi-square test for goodness of fit should be performed with a specified significance level (alpha).

The chi-square test for goodness of fit is used to determine if observed data follows an expected distribution. In this case, we want to test whether the number of customers each day, which is expected to be 15, follows a uniform distribution.

To perform the test, we need to collect data on the number of customers over a period of time and compare it to the expected uniform distribution. The observed frequencies for each category (e.g., the number of days with 0 customers, 1 customer, 2 customers, etc.) would be obtained.

Then, the chi-square test statistic can be calculated based on the observed and expected frequencies. The test statistic measures the discrepancy between the observed and expected distributions.

To interpret the test results, we compare the calculated chi-square value to the critical chi-square value at the chosen significance level (alpha). If the calculated chi-square value exceeds the critical value, we reject the null hypothesis and conclude that the number of customers does not follow a uniform distribution. Conversely, if the calculated chi-square value does not exceed the critical value, we fail to reject the null hypothesis, indicating that the number of customers can be considered to follow a uniform distribution.

Please note that the specific calculations and decision-making process require additional data and the use of statistical software or tables to obtain the critical chi-square value.

b) The sampling frame in this study is the list of colleges and high schools that were visited by the police department.

c) The bias in this survey is called social desirability bias.

Many students who have used cannabis may be afraid or hesitant to admit it to a uniformed police officer due to social stigma, fear of legal consequences, or other reasons.

This can lead to underreporting or inaccurate reporting of cannabis use.

d) The bias that can result from the sampling frame used is known as selection bias.

The sample of students selected may not be representative of the entire youth population in British Columbia.

the moellers drove from new york to san francisco, a distance of 3,000 miles. the first day, they drove of the distance and of the remaining distance on the second day. how many miles did they have remaining to reach their destination?

Answers

The Moellers had 1,500 miles remaining to reach their destination. On the first day, the Moellers drove 1/2 (or 0.5) of the 3,000 miles, which is 1,500 miles. This means they had 1,500 miles remaining to reach their destination.

On the second day, they drove 1/4 (or 0.25) of the remaining 1,500 miles, which is 375 miles. Therefore, they had 1,125 miles remaining to reach their destination after driving 1/2 on the first day and 1/4 on the second day.

Based on the given information, the Moellers drove 1/3 of the distance on the first day and 1/4 of the remaining distance on the second day. Let's calculate the remaining distance to reach their destination:

Total distance: 3,000 miles

First day: 1/3 of 3,000 miles = 1,000 miles

Remaining distance after the first day: 3,000 - 1,000 = 2,000 miles

Second day: 1/4 of 2,000 miles = 500 miles

Remaining distance after the second day: 2,000 - 500 = 1,500 miles

So, the Moellers had 1,500 miles remaining to reach their destination.

How could you use the function y = sin 2x to find the zeros of y = tan 2x

Answers

To find the zeros of y = tan(2x), we need to solve the equation sin(2x) = 0 to determine the x-values where sin(2x) is zero. These x-values will correspond to the zeros of the function tan(2x).

To find the zeros of the function y = tan(2x), we can utilize the fact that tan(x) is equal to sin(x)/cos(x).

Given y = tan(2x), we can rewrite it as:

y = sin(2x) / cos(2x)

Now, let's consider the numerator of this expression, which is sin(2x). If we set sin(2x) equal to zero, we can determine the values of x that make the numerator zero:

sin(2x) = 0

By solving this equation, we can find the zeros of sin(2x). The solutions will be the values of x for which sin(2x) equals zero.

Similarly, we can look at the denominator of the expression y = sin(2x) / cos(2x), which is cos(2x). If cos(2x) equals zero, the denominator will be zero, which leads to undefined values for y. These points will be vertical asymptotes of the function tan(2x).

To find the zeros of y = tan(2x), we need to solve the equation sin(2x) = 0 to determine the x-values where sin(2x) is zero. These x-values will correspond to the zeros of the function tan(2x).
