A golf association requires that golf balls have a diameter that is 1.68 inches. To determine if golf balls conform to the standard, a random sample of golf balls was selected. Their diameters are shown in the accompanying data table. Do the golf balls conform to the standards? Use the α=0.05 level of significance. First determine the appropriate hypotheses. H0: ▼ μ ▼ = H1: ▼ μ ▼ ≠ (Type integers or decimals. Do not round.) Find the test statistic. nothing (Round to two decimal places as needed.)

The United States Golf Association test golf balls to ensure that they conform to the rules of golf (they do not go too far). Balls are tested for weight, diameter, roundness and overall distance. The overall distance test is conducted by hitting balls with a driver swung by a mechanical device known as “Iron Byron” after the legendary great Byron Nelson, whose swing the machine is said to emulate. A total of 100 distances were collected and are available in...

able legs made in your factory are unusable if their diameter is either too large or too small. The target diameter is 4 centimeters, with a known standard deviation of 0.3 centimeters. You take a sample of 5 table legs and find that their mean diameter is 4.2 centimeters. (Assume that the distribution is normal.) For the following, round all answers to no fewer than 4 decimal places. Write the null and alternative hypotheses to determine if the manufacturing process...

Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a friend tells you that the average length of trout caught in Pyramid Lake is μ = 19 inches. However, a survey reported that of a random sample of 51 fish caught, the mean length was x = 18.6 inches, with estimated standard deviation s = 2.6 inches. Do these data indicate that the average length of a trout caught in Pyramid...

3. Pizza! A national pizza chain advertises that its large pizzas are 14 inches in diameter. The CEO wants to determine whether the average size of all of its pizzas adheres to that claim. She collects a random sample of 31 pizzas and measures each one. The sample results in an average diameter of 14.9 inches and a standard deviation of s = 2.10. (a) Identify µ in this scenario. (Choose One) • Average diameter of all pizzas in the...
