Suppоse we hаve а rаndоm variable which takes оne of two values: either -1 or 1. We have such a random variable with probability of being 1 given by where [p]. Find .

Dаtа set оf GPA fоr 15 rаndоmly selected students at a certain college. Assume the population is normally distributed. Using summary stat, first find mean and standard deviation, then find confidence interval. Find a 95% and 90% confidence interval for the mean (average) GPA of all students at that college. Work directly with data set (TStat, with data) to find interval. Do not round number answers. Type or copy paste as in StatCrunch output. The sample mean GPA is [a] Find 95% confidence interval: Lower limit is [i] and upper limit is [j]. Interpret 95% confidence interval: [c] (Enter A, B, C) I am 95% confident that the average GPA of 15 college students is between the lower and upper limit. I am 95% confident that the average GPA of all students at that college is between the lower and upper limit. I am 95% confident that the average GPA of students in all U.S. colleges is between the lower and upper limit. The college district board claims that the mean GPA of its students is more than 2.5. How reliable is the college board's statement. Conclude based on 95% interval. [d] (Enter A, B, C, D) The college board's claim is right. The sample mean GPA of 15 students at the college is much higher than 2.5. The college board's claim is right. The mean GPA of all students at the college could go as high as 3.23, which is much higher than 2.5. The college board's claim is wrong. The mean GPA of all students at the college could go much lower than 2.5. The college board's claim is wrong. We cannot conclude about the mean GPA of all students at the college using a small sample. Find 90% confidence interval: Lower limit is [g] and upper limit is [k]. The college board claims that the mean GPA of it students is more than 2.5. How reliable is the college board's statement. Conclude based on 90% confidence interval. [h] (Enter A, B, C) The college board's claim is wrong. We cannot conclude about the mean GPA of all students at the college using a small sample. The college board's claim is right. The upper limit for the mean GPA confidence interval is much higher than 2.5. The college board's claim is right. The sample mean GPA of 15 students at the college is much higher than 2.5. The college board's claim is right. The lower limit for the mean GPA confidence interval is higher than 2.5.
