Answer:
The population mean is 5 volts
Step-by-step explanation:
Output voltage is assumed to be normally distributed, with standard deviation 0.25 Volts
s=0.25
n = 8

Sample mean = 
Since n < 30 and population standard deviation is unknown
So, we will use t test
Formula : 

t=-1.69
Refer the t table for p value
Degree of freedom = n-1 = 8-1 = 7
So,
P value >α
So, We are failed to reject null hypothesis
Hence The population mean is 5 volts
Answer:
No. Of slices my friend eats = No. Of slices eaten by me - No. Of slices my friend eats fewer than me
= 5 - 2
= 3
