6.24 Sleep deprivation, CA vs. OR, Part II. Exercise 6.22 provides data on sleep deprivation rates of Californians and Oregonians. The proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 8.0%, while this proportion is 8.8% for Oregon residents. These data are based on simple random samples of 11,545 California and 4,691 Oregon residents. (a) Conduct a hypothesis test to determine if these data provide strong evidence the rate of sleep deprivation is different for the two states. (Reminder: Check conditions) (b) It is possible the conclusion of the test in part (a) is incorrect. If this is the case, what type of error was made?

Dr. Ingrid is conducting an experiment to see whether time spent reading is related to poor vision. To do so, she creates three groups and randomly assigns 17 participants to each: the first group reads for 30 min a day, the second group reads for 1hr a day, and the third group reads for 1.5 hrs a day. Dr. Ingrid plans on using a one-way ANOVA to analyze the results of her experiment. If Dr. Ingrid has set alpha to .01, what will be her critical value of F?
Researchers conducted a study investigating the number of viralinfections people contracted as a function of their stress over a 6-month period. Use the provided steps to conduct a one-factor between-subjects ANOVA that test whether there are any differences in number of infections across the four conditions.a. State the hypotheses. b. Determine the critical value for an alpha level of 0.05.
State the Result: A hypothesis test was conducted at the alpha = 0.01 level of significance. The test resulted in a p-value of 0.044.
A study of the population of NUIG students showed that out of a sample of 155 students surveyed, 45 said they regularly cooked their own food during term time.Carry out a hypothesis test to determine if this gives evidence that more than 25% of the population of NUIG students regularly cooked their own food during term time, i.e test the hypotheses for true population proportion, H0: p= 0.25 versus Ha: p > 0.25, at significance level α = 0.05 Complete the test by filling in the blanks in the following: An estimate of the population proportion is . The standard error is . (3 dec places) The distribution is (examples: normal / t12 / chisquare4 / F5,6). The test statistic has value TS=. (2 dec places) Testing at significance level α = 0.05, the rejection region is: greater than (2 dec places). There (is / is no) evidence to suggest that the true proportion of the population of all NUIG students who regularly cooked their own food during term time, p, is greater than 0.25.

Let’s say that I want to test a hypothesis that drivers who are pooled over driving a sports car receive speeding fines that are higher than drivers operating other types of cars. Using a large sample (n over 30), I find that Zobt=1.87 Is this difference statistically significant (i.e., would I reject the null) at α=0.05 level? Why/why not?
