# Imagine you wish to determine whether the mean number of hours worked per week by men in a sample differs from the 40-hour standard.

1. Imagine you wish to determine whether the mean number of hours worked per week by men in a sample differs from the 40-hour standard. Use the information below to calculate the value of the single-sample t statistic

Range =60

Min Value= 5

Max value= 65

Mean= 42.31

Variance=100.00

Standard deviation= 10.00

Sum= 1,227

# of observations= 29

single-sample t statistic is given by t= ( x̄ - μ)/(s /sqrt(n)) in... View the full answer

T test statistic = (xbar - ﻿ μ ﻿ ) / (s/sqrt(n)) = (42.31- 40) /... View the full answer
