- A hypothesis test is conducted with H0 : µ = 18 vs. Ha: µ > 18. Given that the population is normal and the sample finds x̅ = 21.2, σ = 10, and n = 9 , the tail area of this test is P =Consider the value of t such that the area to the left of −|t|−| plus the area to the right of |t| equals 0.05 Step 2 of 2 : Assuming the degrees of freedom equals 4, select the t-value from the t-distribution table.A meal box enterpreneur wants to know how the meal box size (in centimeters) of parents compares to the meal box size of their children. For a sample of seven parents and their children, the value of the test statistic for the Wilcoxon signed-rank test for a matched pairs sample is T = T+ = 27. The differences are calculated as the parent's meal box size subtracted by the child's meal box size. Specify the competing hypothesis to determine if the median difference in meal box size between parents and children is greater than zero. At the 5% significance level, what is the critical value? At the 5% significance level, what is the decision and conclusion?
- For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10. The 50 paired ratings yield x=6.3, y=6.0, r=−0.257, P-value=0.072, and y=7.92−0.300x. Find the best predicted value of y (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is x=3. Use a 0.05 significance level. The best predicted value of y when x=3 is? (Round to one decimal place as needed.)Suppose a researcher uses 36 pairs of identical twins (i.e., dependent data) to compare two treatments.

In evaluating the calculated t value, how many degrees of freedom (df) does the researcher have?A. 36B. 72C. 35D. 37For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10. The 50 paired ratings yield x=6.3, y=5.9, r=−0.256, P-value=0.073, and y=7.73−0.285x. Find the best predicted value of y (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is x=6. Use a 0.01 significance level. The best predicted value of y when x=6 is?
