Question

Based on your reasoning that the location of the second hand of a clock when the teacher walks through the
door would be uniformly distributed from 0 to 60 seconds.
1) For simple random samples of size ? = 30 , determine the mean of the sampling distribution of ?̅ , ? ?̅ ,
and standard deviation of the sampling distribution of ?̅ , ? ?̅ .
2) Determine the probability of the mean of ? for a sample of size 30 will be between 27 and 33 seconds,
i.e., ? (27 < ?̅ < 33)

Based on your reasoning that the location of the second hand of a clock when the teacher walks through the door would be uniformly distributed from 0 to 60 seconds. 1) For simple random samples of size n = 30, determine the mean of the sampling distribution of x, μ Ñ, and standard deviation of the sampling distribution of x, x. 2) Determine the probability of the mean of x for a sample of size 30 will be between 27 and 33 seconds, i.e., P (27<x<33)
