6. In ECON 2106, I have 31 females and 24 males. Via a survey, the females state that they study 5.4 hours per week (with standard deviation of 2.3) and the males state that they study 4 hours per week (with standard deviation of 2.6). I want to see whether they study equal amounts statistically.
(a) Write down an appropriate null and alternative hypothesis. (b) Construct the test statistic. (c) Test your hypothesis at all appropriate levels.

Answer #1

Generally we use alpha as 0.05 or 0.01 so overall conclusion is to reject the null hypothesis.

Conclusion- they did not study equal amounts statistically.

The author randomly selected 150 females and 150 males from the California Health Survey and obtained these results: Among the 150 females, the mean age is 59.6 years and the standard deviation is 17.7 years: among the 150 males, the mean age is 59.1 years and the standard deviation is 16.9 years. Using a 0.05 significance level, is there sufficient evidence to support the claim that the mean age of an adult California female is the same as the mean...

QUESTION 24 A study examines fitness differences between males and females. A chi-square test of association is used to test the results. The results are displayed in the following table: Gender Fit Not Fit Total X2,df p Male     n (%) 24 (41.8%) 34 (58.6%) 58 5.76, 1 .02 Female n (%) 34 (64.2%) 19 (35.8%) 53 Total 58 53 111 The most appropriate interpretation of these results is: 1. Fitness levels were similar in men and women. There is no siginficant...

1. (Hypothetical) The General Social Survey measures the number of hours that individuals spend on the internet each week. Males use the Internet 12.1 hours per week. (standard deviation 10.8; N = 264), while women use the Internet 9.10 hours per week (standard deviation 12.50; N = 300). a) Test the research hypothesis that men use the internet more hours a than women. Set alpha at .05. b) Would your decision have been different if alpha were set at .01?

Question 1. A class survey of 400 students was given in which students at College ABC claimed to study an average of 15.8 hours per week. Consider these students as a simple random sample from the particular population of College ABC students. We want to investigate the question: Does the survey provide good evidence that students study more than 15 hours per week on average? Assume the population of hours studied is normal with a standard deviation of 4. a)...

In a survey of a SRS of 463 first-year college students the students were asked about studying habits. Among these students the mean response of studying time was 15.3 hours. Suppose we know that study time among similar students varies with standard deviation 8.5 hours. Does this study give statistically significant evidence at the 0.05 significance level that students generally claim to study more than 15 hours per week on average?  For full credit, perform a complete significance test (that is,...

Do students study less than 150 minutes (2.5 hours), on average, each week? A survey of 51 randomly selected students finds that on average students study 138 minutes per night with a standard deviation of 32 minutes. A hypothesis test based on this data produces a test statistic of -2.68 and a p-value of 0.005. What are the appropriate decision and conclusion at the 5% significance level? Select one or more: Reject the null hypothesis. Do not reject the null...

Hypothesis testing: A student group claims that first-year students at a university must study 2.25 hours per night during the school week. A skeptic suspects that they study less than that on average. A class survey finds the study time claimed by 259 students is 147 minutes. Regard these students as a random sample of all 1st year students and suppose what study times follow a Normal Distribution with a population standard deviation 62 minutes. Test to see if the...

A class survey in a large class for first-year college students asked, "About how many hours do you study during a typical week?" The mean response of the 468 students was x = 15.3 hours. Suppose that we know that the study time follows a Normal distribution with standard deviation σ = 8.5 hours in the population of all first-year students at this university. Regard these students as an SRS from the population of all first-year students at this university....

A survey in a large class for first-year college students asked, "About how many hours do you study during a typical week?" The mean response of the 461 students was x = 15.3 hours. Suppose that we know that the study time follows a Normal distribution with standard deviation σ = 8.5 hours for all first-year students at this university. Does the survey results provide evidence (at the 0.05 level) of students claiming to study more than 15 hours per...
