A company manufacturing computer chips has an allowable rate of 5% for computer chips off the assembly line. In July, there was an 8% failure rate for 1052 chips. They want to know if this rate is higher than normal. Create a 95% confidence interval for the sample proportion of 8% for July.

95% CI:
Lower Bound_____
Upper Bound_____
ME for CI_____

Explain what the company can say about their failure rate from this 95% CI?

With regards to this CI, is 5% a possible failure rate for July or do the machines need to be recalibrated? Why?
