The "domain" would be the the x values.
Answer: -4, -2, 0, 2, 4
<span>The difference of X and the number is six what is the other number.
Write "the difference between X and another number (Y) is 6." Find Y.
X-Y=6, or Y = X - 6 This is the equation of a straight line. Can't solve this problem for Y without knowing more about X. Ensure that you have copied down ALL of the original problem.</span>
The answer should be x=133
Answer:
We are given that The valve was tested on 150 engines and the mean pressure was 7.7 lbs/square inch.
We are also given that the valve was designed to produce a mean pressure of 7.6 lbs/square inch
So,
Null hypothesis:
Alternate hypothesis :
Since n > 30 and population standard deviation is given
So, We will use z test
Formula :
Substitute the values
refer the z table for p value
so, p value is 0.9927
Since it is a two tailed test So, p = 2(1- 0.9927) = 0.0146
α = 0.1
p value< α
So, we reject null hypothesis
Hence There is sufficient evidence at the 0.1 level that the valve does not perform to the specifications
