-79.3 -79.3 incorrect 0.8 0.8 correct 52 52 correct At least one of the answers above is NOT correct. (1 point) Heights (in centimeters) and weights (in kilograms) of 7 supermodels are given below. Find the regression equation, letting the variable Heigth be the independent (x) variable, and predict the weight of a supermodel who is 171 cm tall. Height 172 168 174 176 172 174 178 Weight 53 50 54 55 52 55 58 The regression equation is y = -79.3 + 0.8 X. The predicted weight of a supermodel who is 171 cm tall is 52.0 kilograms. Note: Round your answers to 1 decimal place. For intermediary computations also round values to 1 decimal place, if needed.(1 point) A sample of 5 measurements, randomly selected from a normally distributed population, resulted in a sample mean, x = 7.5 and sample standard deviation s = 1.56. Using a = 0.1, test the null hypothesis that the mean of the population is 5.9 against the alternative hypothesis that the mean of the population, M
