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:
w = 5
Step-by-step explanation:
(3w - 1) ÷ 3 - (2w + 1) ÷ 3 = 1
(Graph, just switch w to x)
