In: Statistics and Probability
You are working on a manufacturing process that should produce products that have a diameter of 3/4 of an inch. You take a random sample of 35 products and find the diameter to be 13/16 of an inch with a standard deviation of 5/32 of an inch. 1. Considering a t% level of significance, what can you state statistically about the process? Please include a null hypothesis, an alternative hypothesis, and use an appropriate test statistic (I.e. Zstat or Tstat).
Hence,there is enough evidence to conclude that the the process is producing products with diameter different than 3/4 inch at 5% level of significance.
