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
the expression millimeters per second , after simplification we get
Given
The company uses the expression millimeters per second to calculate the maximum capacity with area
Lets apply the property of exponents to simplify the expression
We apply power property of exponents.
If we have exponent inside and outside the parenthesis then we multiply it
we distribute outside exponent inside the parenthesis
In the given expression , 2 has exponent 1
The simplified expression after applying the property is
