With
a standard deviation of 6 minutes, we will test the hypothesis that σ = 6
against the alternative that σ < 6 if a random sample of the test
times of 20 high school seniors has a standard deviation s = 4.51. use a
0.05 level of significance.

Answer:
The standard deviation of the sampling distribution of x overbarx, denoted sigma Subscript x overbarσx, is called the standard error of the mean . The standard deviation of the sampling distribution of x overbarx, denoted sigma Subscript x overbarσx, is called the standard distribution of the sample.
Step-by-step explanation:
The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. It is called the standard error of the mean (SEM) if the parameter or the statistic is the mean.
The answer should be 41 Inches
29^+29^2=1682
41.0121933088^2=1682
Rounding to the nearest tenth makes it 41 Inches
