WORKSHEET #4 - TEST OF DIFFERENCEDirection: Answer the following items.A nationwide survey found out that the average time that college students spent on theirpersonal computer is 10.5 hours per week. A random sample of 28 college students showedthat they spent 8.5 hours per week using their computers with a standard deviation of 1.2hours. Test whether the average number of hours spent by the 28 college students issignificantly higher than the national average of 10.5 hours. Use a level of significance of5%.1. GIVEN: (choose the best answer. Write the letter and the answer,U.=8.5 hours, n = 28 college students, * = 10.5 hours, s = 1.2 hours, a = 0.05= 10.5 hours, n = 28 college students, = 8.5 hours, s = 1.2 hours, a = 0.05O.A.= 8.5 hours, n = 10.5 hours, = 28 college students, s= 1.2 hours, a = 0.052. STEP 1: IDENTIFY THE CLAIM AND FORMULATE THE HYPOTHESES (choose thebest answer.

Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a friend tells you that the average length of trout caught in Pyramid Lake is μ=20 inches. However, a survey reported that of a simple random sample of 37 fish caught, the mean length was 17.5 inches, with an estimated standard deviation of 4.3 inches. Do these data indicate that the average length of a trout caught in Pyramid Lake is less than μ=20 inches? Use α=0.05. What is the value of the test statistic? (Round your answer to two decimal places.)Find the P-value. (Round your answer to four decimal places.)Based on your results, will you reject or fail to reject the null hypothesis? Are the data statistically significant at level αα? A) At the α=0.05α=0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. B) At the α=0.05α=0.05 level, we reject the null hypothesis and conclude the data are statistically significant. C)…

Airline companies are interested in the consistency of the number of babies on each flight, so that they have adequate safety equipment. They are also interested in the variation of the number of Babies. Suppose that an airline executive believes the standard deviation in the number of babies is 6 at the most. The airline conducts a survey. The results of the 23 flights surveyed give a samle mean of 8 with a sample standard deviation of 9. Test the executive's belief to see if it is accurate, or if it is actually greater at the a = 0.05 level.

A college in the northeastern United States used SAT scores to help decide which applicants to admit. To determine whether the SAT was useful in predicting success, the college examined the relationship between the SAT scores and first-year GPAs of admitted students. The average math SAT score of a sample of 200 randomly selected students was 649.5 with a standard deviation of 66.2. The average GPA of the same students was 2.63 with a standard deviation of 0.58. The correlation between GPA and math SAT score was 0.19. (a) What does the correlation of 0.19 tell us about SAT scores and GPA scores? (You need to provide two answers.)(b) Find the equation of the least squares regression line.(c) Using the equation, predict the GPA score of a person with a math SAT score of 650.(d) Using the equation, predict the GPA score for a person with a math score of 800.
