Answer:
E. There is sufficient evidence that the mean of the pressure required to open a certain valve has increased.
Step-by-step explanation:
Null hypothesis(H0): μ= 8.4 psi
Alternative hypothesis (H1): μ> 8.4 psi
If the test was due with a representative minimum number of observations. And, if the null hypothesis was rejected, then the mean pressure required to open a valve is greater than 8.4 psi. We can conclude that (at a certain level of confidence) there is sufficient evidence that the mean of the pressure required to open a certain valve has increased.
