Answer:
Step-by-step explanation:
sample size ( n ) = 2500 women ( computer and mathematical occupations )
Average earnings of sample ( X )= $75000 / year
standard deviation ( s )= $9500
a) knowing that the average earnings of men are $89,000/year, the null and the alternative hypotheses that the average earnings of women match the average earnings of men in the population.
Given ; Ц = $89000
Null hypothesis ( H0) : Ц = $89000
Alternative hypothesis ( H1 ) : Ц ≠ $89000
The test is : one sample t test hypothesis
b) Test statistic
Test statistic ( t ) =
The answer is a, 21. 21x3 is 63. 63 + 1 = 64.
