First subtract 11

Then divide by negative four
Then you'll get x= 2
So the answer is 2
Answer:
There is no statistical evidence to support the claim that the mean is elss than 74.
Step-by-step explanation:
Given that a paint-drying situation in which drying time for a test specimen is normally distributed with s = 6.
The hypotheses H0: µ = 74 and Ha: µ < 74
are to be tested using a random sample of n = 25 observations
a) Z = 
ie. -1.417 std deviations to the left of mean.
b) p value = 0.078241
Since p > 0.01 , our alpha, accept H0
There is no statistical evidence to support the claim that the mean is elss than 74.

Step-by-step explanation:
Answer:
Hello,
I think -2p < - 10 goes with graph one
Then -M = 8 > 6 goes to Graph Two
Next 13 > 4r + 5 goes to Graph three
Last but not least -7 - Z < -1 goes to Graph Four
If I am Wrong i am sorry
