Expert Solution

1. A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. We can use test statistic to determine whether to reject the null hypothesis or not. The test statistic compars your data with what is expected under the null hypothesis. The test statistic is used to calculate the p value.

3. Two sample proportion test is used to determine whether the range of values that is likely to include the difference between the proportion.

What test statistic would we use when comparing two population proportions? What test statistic would we use when comparing observed vs. expected frequencies? If my degrees of freedom were 7 and I am comparing observed and expected frequencies at a 0.01 level of significance. What would my critical value be?

Explain when you use the χ 2-Test for Independence/Homogeneity and when you use the χ 2-Test for Goodness-of-Fit. Why do you not compute a confidence interval for these two tests. (You should give at least two reasons.)

The test statistic of z = -1.98 is obtained when testing the claim that p < 0.64. A) Using a significance level of alpha = 0.05, find the critical value(s). b. Should we reject Upper H 0 or should we fail to reject Upper H 0? Please answer A and B note For part A *(Round to two decimal places as needed. Use a comma to separate answers as needed*

1. For the standardized test statistic approach to hypothesis testing, calculate the test statistic for testing the null hypothesis that the population mean is less than or equal to 9.29, given a sample mean of 13.90, a sample size of 35, and a population standard deviation of 3.92. Round to two decimals. 2. Using the traditional hypothesis testing approach, calculate the critical value for testing the null hypothesis that the population mean is greater than or equal to 13, given...

The test statistic of z=1.42 is obtained when testing the claim that p does not = 0.663. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of alphaequals0.05, should we reject Upper H 0 or should we fail to reject Upper H 0?

2. Write a simulation in R that shows the distribution of the t-test statistic when the null hypothesis is true. To do this, you should use a for loop that repeatedly performs t-tests comparing sample means of data that come from distributions with the same population mean and standard deviation. Use rnorm() to take samples, t.test() to perform the t-tests, and use “$statistic” to extract the t-test statistic from the t.test() procedure (e.g. t.test(x,y)$statistic). Make a histogram of the test...
