The results indicated that 8​% of the males and 17​% of the females answered window tinting. The poll description did not state the sample sizes of males and females. Suppose that both sample sizes were 473 and that 40 of 473 males and 80 of 473 females reported window tinting as their preferred luxury upgrade of choice.    b. Find the​ p-value in​ (a) and interpret its meaning.   The​ p-value is _______ ​(Round to three decimal places as​ needed.)   Interpret the​ p-value.   The​ p-value is the probability that in a random sample of 946 ​adults, the difference between the proportions of males and females who said they prefer window tinting as a luxury upgrade will be _________the difference in this​ sample, assuming that the proportion of males who said they prefer window tinting as a luxury upgrade is ________the proportion for females…
A manufacturer of household appliances wanted to determine if there was a relationship between family size and the size of washing machine purchased. The manufacturer was preparing guidelines for sales personnel and wanted to know if the sales staff should make specific recommendations to customers. A random sample of 300 families was asked about family size and size of washing machine. For the 40 families with one or two people, 25 had an 8-pound washer, 10 had a 10-pound washer, and 5 had a 12-pound washer. The 140 families with three or four people included 37 with the 8-pound washer, 62 with the 10-pound washer, and 41 with the 12-pound washer. For the remaining 120 families with five or more people, 8 had an 8-pound washer, 53 had a 10-pound washer, and 59 had a 12-pound washer. Based on these results, what can be concluded about family size and size of washer? Construct a two-way table, state the hypothesis, compute the statistics, and state your conclusion.
A study was recently conducted to assess the relationship between miscarriage and heavy alcohol use during the first trimester of pregnancy. Fifty women who suffered miscarriage were enrolled in the study along with 50 women who delivered full-term infants. Each participant’s use of alcohol during their first trimester of pregnancy was ascertained by face-to-face interview. For the purpose of this study, heavy alcohol use was defined as consuming four or more drinks on any one occasion during the first trimester of pregnancy. Study results found that a total of 18 women were heavy alcohol users, 14 among those who suffered a miscarriage. 1) What type of study design was used? Explain. 2) Set up the 2X2 contingency table for the data. 3) For this type of study design, what is the appropriate measure to describe the strength of the association between exposure and disease? 4) Calculate the measure identified in question 3. 5) Interpret the measure calculated in question 4. A recent study…
