An urban comminity would like to show that the incidence of breast cancer is higherin their area than in a nearby rural area. If it is found that 20 out of 200 adultwomen in the urban comminity have breast cancer and 20 of 300 adult womenin the rural community have breast cancer, can we conclude at the 0.025 level of1significance that breast cancer is more prevalent in the urban comminity?

The question is about hypo. testing Given : Selected no. of adult women from urban area ( n1 ) = 200…

The General Social Survey (GSS) asked this question: “Have you attended religious services in the last week?” Here are the responses for those whose highest degree was high school or above Carry out the chi-square test for the hypothesis of no relationship between the highest degree attained and attendance at religious services in the last week. What do you conclude? Make a table by omitting the column corresponding to those whose highest degree was high school. A) Carry out the chi-square test for the hypothesis of no relationship between the type of advanced degree attained and attendance at religious services in the last week. What do you conclude? B)Make a 2×3 table by omitting the column corresponding to those whose highest degree was high school.

The leader of two postpartum women’s support groups is interested in the depression levels of the women in her groups. She administers the Center for Epidemiologic Studies Depression Scale (CES-D) screening test to the members of her groups. The CES-D is a 20-question self-test that measures depressive feelings and behaviors during the previous week. The mean depression level from the screening test for the 10 women in the first group is μ₁ = 16; the mean depression level for the 14 women in the second group is μ₂ = 10. Without calculating the weighted mean for the combined group, you know that the weighted mean is:
The proportion P residence in a community recycles traditionally been 70%. Policymaker claims of the unfortunate less than 70% now that one of the recycling centers has been relocated.

A study was done to see the effect of sleep schedule on hand “steadiness”, which is an important trait for surgeons. Four different sleep schedules are of interest. The study has ten different subjects available for the experiment. To test, hand steadiness is measured for each subject at each of the four different sleep schedules, for a total of 40 measurements. Can you conclude that the average score on the hand steadiness test is different for the four different sleep schedules? Which test would you use to analyze the data? a) t-test b) ??td-test c) ANOVA for CR-k d) ANOVA for RB-k e) Chi-square Goodness of fit f) ??tp-test
