please answer both questiosn 1 and 2 and all the subs 1. Suppose the confidence interval (0.6358, 0.7532) represents the proportion of Skyline College students who say math is their favorite subject. a. Based on the confidence interval, is it likely 60% of Skyline College students say math is their favorite subject? No, 0.60 is not contained in the interval Yes, 0.60 is not contained in the interval Yes, all the interval values are greater than 0.60 b. Based on the confidence interval, does it appear that more than 60% of Skyline College students say math is their favorite subject? Yes, all the interval values are greater than 0.60 Yes, 0.60 is not contained in the interval No, 0.60 is not contained in the interval c. Based on the confidence interval, does it appear that fewer than 60% of Skyline College students say math is their favorite subject? No, 0.60 is not contained in the interval Yes, all the interval values are greater than 0.60 No, all the interval values are greater than 0.60 2.

A researcher investigated whether the temperature of milk, x, can be used to predict the milk's pH content, y. She predicted the pH level of a glass of milk with a temperature of 8.45 degrees to be ŷ= 6.795 a)A 95% confidence interval for the mean pH of all milk with temperature 8.45 degrees is calculated to be (6.76, 6.83). Which of the following is the correct interpretation of this confidence interval? -The mean pH level for all glasses of milk having a temperature of 8.45 degrees is somewhere between 6.76 and 6.83, with 95% confidence. -The pH level for one glass of milk with a temperature of 8.45 degrees is somewhere between 6.76 and 6.83, with 95% confidence. -There is a probability of 0.95 that the mean pH level for this glass of milk with temperature 8.45 degrees is between 6.76 and 6.83. -95% of all glasses of milk with a temperature of 8.45 degrees have a pH level between 6.76 and 6.83.   b)Suppose we have a glass of milk whose temperature is 8.45 degrees. We…
