Do male and female servers work the same number of hours? A sample of 25 female servers worked an average of 26 hours per week,

Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

Given that

Group Group One Group Two

Mean 26.00 23.00

SD 2.00 4.00

SEM 0.40 1.21

N 25 11

where group I represents female servers and group II male servers.

We have to calculate confidence interval for 90% for difference in means

The mean of Group One minus Group Two equals 3.00

df = 34

standard error of difference = 0.993

t critical = 2.034 for 90% df 34

Hence confid. interval at 90%

=Mean diff ±2.034 * std error of diff

= (0.98, 5.02)
