A) A research shows families spend average of $52 for eating out each week. Population standard deviation was $12. There were 36 samples.

Second researcher claims the actual money spent is less than $42 per week.

What would be the null hypothesis?

B) What would be the alternative hypothesis?

C) What kind of test are we looking at?

D) Find the critical value

E) Given the information, would you reject the null hypothesis or fail to reject the null hypothesis?

You will perform a Chi-Square test and an ANOVA test. For each hypothesis test make sure to report the following steps: Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original...

A geriatric research project has been tracking the health and cognitive functions of the elderly population in Arizona. The table below shows the memory test scores from 16 elderly residents, tested first when they were 65 years old and again when they were 75 years old. The researcher wants to know if there is a significant decline in memory functions based on this sample. The alpha level was set at α = .05 for the hypothesis test. Memory score Subject...

Patients recovering from an appendix operation normally spend an average of 6.3 days in the hospital. The distribution of recovery times is normal with a ? = 2.2 days. The hospital is trying a new recovery program designed to lessen the time patients spend in the hospital. The first 25 appendix patients in this new program were released from the hospital in an average of 5.5 days. On the basis of these data, can the hospital conclude that the new...

The New York Times reported that the average length of stay for 42 patients in NYC hospitals was 23 hours with a standard deviation of 2.5 hours. It reported that the average length of stay for 36 patients in the suburbs was 23.8 hours with a standard deviation of 3.4 hours. At the 1% level of significance, is the length of time a patient stays in the hospital significantly longer in the suburbs? (1) List all the information necessary for...

Do shoppers at the mall spend more money on average the day after Thanksgiving compared to the day after Christmas? The 60 randomly surveyed shoppers on the day after Thanksgiving spent an average of $150. Their standard deviation was $35. The 56 randomly surveyed shoppers on the day after Christmas spent an average of $133. Their standard deviation was $32. What can be concluded at the α = 0.10 level of significance? For this study, we should use t-test for...

A sample of size 234, taken from a normally distributed population whose standard deviation is known to be 5.70, has a sample mean of 75.54. Suppose that we have adopted the null hypothesis that the actual population mean is greater than or equal to 76, that is, H0 is that μ ≥ 76 and we want to test the alternative hypothesis, H1, that μ < 76, with level of significance α = 0.1. a) What type of test would be...

Suppose that we have adopted the null hypothesis that the actual population mean is greater than or equal to 93, that is, H0 is that μ ≥ 93 and we want to test the alternative hypothesis, H1, that μ < 93, with level of significance α = 0.05. a) What type of test would be...
