Prepare a nice bar chart comparing the average compressive and tensile strength of each mix. Plot the average value along with a 95% confidence interval of this average value. (Similar to the one you made in Activity 8.)
Separate modeling efforts indicated that the ideal mix must have a compressive strength greater than 800 psi. Using the hypothesis testing framework, write null and alternative hypotheses and then test each mix. Report the hypothesis testing results, along with the p-value.
Additionally, the ideal mix must have a tensile strength greater than 175 Repeat step 2 now testing the tensile strength
Based on your results from 2 and 3 are there any mixes that satisfy both criteria as determined through hypothesis testing with a p-value less than 0.05?
Answer the following questions based on the above analysis

Modeling efforts indicated that the ideal mix must have a compressive strength greater than 800. Using the hypothesis testing framework described in the lecture, write null and alternative hypotheses. Choose the correct null and alternative hypothesis pair from the choices below.
H0:800
HA:>800
H0:>800
HA:800
H0:800
HA:=800
H0:=800
