A manufacturer produces plastic golf tees The injector molde

A manufacturer produces plastic golf tees. The injector molder produces golf tees that are designed to have an average height of 69 mm. To determine if this specification is met, random samples are taken from the production floor. One sample is contained in the table below. Click the icon to view the data table. Determine if the process is not producing the tees to specification. Use a significance level of 0.01. If the hypothesis test determines the specification is not being met. the production process will be shut down while causes and remedies are determined. At times this occurs even though the process is functioning to specification What type of statistical error would this be? State the appropriate null and alternative hypotheses. Choose the correct answer below. H_0: mu lessthanorequalto 69 H_A: mu > 69 H_0: mu > 69 H_A: mu lessthanorequalto 69 H_0: mu = 69 H_A: mu notequalto 69 H_0:mu notequalto 69 H_A: mu = 69 H_0: mu greaterthanorequalto69 H_A: mu
