I have class in a half an hour and I still haven't solved all of the hw questions... please help guys I'll give 90 points and br
ainliest for the first correct answer with brief explanation: thank you SOOOOOOOOOO much!

Answer:
a. The null and alternative hypothesis are
b. P-value = 0.7181
c. The process should not be recalibrated. We have no enough statistical proof with this sample that the mean is not 23% (the null hypothesis π=23% could not be rejected).
Step-by-step explanation:
We want to know if there is enough statistical evidence to claim that the mean of the process is not 23%.
Then, the null and alternative hypothesis are
We assume a significance level of 0.05.
The sample of size N=10 has a p=0.232.
The standard deviation to is
The test statistic z is given by
The two-tailed P-value for z=-0.361 is P=0.7181. This value is bigger than the significance level, so the effect is not significant. The null hypothesis can not be rejected.
That means we have no statistical proof with this sample that the mean is not 23%. The process should not be recalibrated.
