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)

I need the answer ASAP
iVinArrow [24]

Answer:

5

Step-by-step explanation:

When squaring the number 5 (i.e 5^2 ) the answer is 25. 5^{2} is the same thing as 5 times 5. Basically with the square root, you are going backwards, so you are therefore finding the base of it all.
