1. Bottles of a popular soda are supposed to contain 300 milliliters of soda. The volume of soda in the bottles distributes approximately normally. An inspector measured the contents of six randomly selected bottles. The results, in milliliters, were 299.4, 297.7, 301.0, 298.9, 300.2, and 297.0. At a 10% level of significance, would you say the manufacturer is meeting their obligation that the bottles contain 300 milliliters of soda? Use technology to find the mean and standard deviation of the...

A soft drink company produces bottles of cola that are supposed to contain 10 ounces. When the bottling machine is working correctly, the number of fluid ounces per bottle is in fact normally distributed with mean 10 ounces and standard deviation 0.42 ounces. A customer buys nine bottles of this type of cola. What is the probability that the average volume of cola in the nine bottles is more than 9.7 ounces but less than 10.2 ounces? (A) 0.9074 (B)...

The Kirkland Company produces plastic bottles to customer order. The quality inspector randomly selects four bottles from the bottle machine every time (considered as one sample) and measures the outside diameter of the bottle neck, a critical quality dimension that determines whether the bottle cap will fit properly. The dimensions (in.) from the last six samples (each sample contains 4 bottles) are Sample Bottle #1 Bottle #2 Bottle #3 Bottle #4 1 0.624 0.627 0.584 0.600 2 0.597 0.601 0.607...

9.29 Lazurus Steel Corporation produces iron rods that are supposed to be 36 inches long. The machine that makes these rods does not produce each rod exactly 36 inches long. The lengths of the rods are approximately normally distributed and vary slightly. It is known that when the machine is working properly, the mean length of the rods is 36 inches. The standard deviation of the lengths of all rods produced on this machine is always equal to.035 inch. The...

Question 15 1 pts A local juice manufacturer distributes juice in bottles labeled 12 ounces. A government agency thinks that the company is cheating its customers. The agency selects 50 of these bottles, measures their contents, and obtains a sample mean of 11.6 ounces with a standard deviation of 0.70 ounce. Use a 0.01 significance level to test the agency's claim that the company is cheating its customers. o test statistic--4.04; critical value = -2.326;...

Question 12 pts The length of time a person takes to decide which shoes to purchase is normally distributed with a mean of 8.21 minutes and a standard deviation of 1.90. Find the probability that a randomly selected individual will take less than 6 minutes to select a shoe purchase. Is this outcome unusual? Group of answer choices Probability is 0.88, which is usual as it is greater than 5% Probability is 0.12, which is usual as it is not...
