Question

A premium golf ball production line must produce all of its balls to 1.615 ounces in order to

get the top rating (and therefore the top dollar). Samples are drawn hourly and checked. If the

production line gets out of sync with a statistical significance of more than 1%, it must be

shut down and repaired. This hour’s sample of 18 balls has a mean of 1.611 ounces and a

standard deviation of 0.065 ounces. Do you shut down the line?

Step 1: Determine the null hypothesis

H0 : μ = 1.615 Ha : μ

Let's Practice T Test A premium golf ball production line must produce all of its balls to 1.615 ounces in order to get the top rating (and therefore the top dollar). Samples are drawn hourly and checked. If the production line gets out of sync with a statistical significance of more than 1%, it must be shut down and repaired. This hour's sample of 18 balls has a mean of 1.611 ounces and a standard deviation of 0.065 ounces. Do you shut down the line? Step 1: Determine the null hypothesis Ho: µ = 1.615 Ha: µ Step 2: Two tailed Step 3: Select significance level a = Step 4: T test Step 5. Find the critical values (in the T-table). Draw and label a graph. 6: Calculate test Statistic N= X = S= Calculate. Step 7-9. State the conclusion: consider the questions provided below Reject? Or fail to reject? Is therea statistically significant difference between the population mean of 1.615 and the sample mean of 1.611? Include the scientific notation for T test.
