(1 point) The manufacturer of cans of salmon that are supposed to have a net weight of 6 ounces tells you that the net weight is actually a normal random variable with a mean of 6.19 ounces and a standard deviation of 0.23 ounce. Suppose that you draw a random sample of 37 cans. Find the probability that the mean weight of the sample is less than 6.14 ounces. Probability =
How much is in that can? A machine that fills beverage cans is supposed to put 12 ounces of beverage in each can. Followin are the amounts measured in a simple random sample of eight cans. 12.09 11.98 12.16 12.03 12.12 12.20 12.10 12.18 Send data to Excel Perform a hypothesis test to determine whether the mean volume differs from 12 ounces. Use the a=0.01 level of significance and the P-value method with the TI-84 Plus calculator. Part 1 of...
help solve The average fill volume for a soda company's cans is supposed to be 16 ounces. The filling machine has a known standard deviation of 0.14 ounces. Each week, the company selects a simple random sample of 30 cans and carefully measures the volume in each can. The results are provided in the accompanying table. Based on the data in the sample, what would you conclude about whether the filling process is working as expected? Base your answer on...

(a) What is the probability that the average weight of a bar in a Simple Random Sample (SRS) with five of nswer to at least 4 decimal places these chocolate bars is between 7.98 and 8.3 ounces? Give your a ANSWER: (b) For a SRS of five...
part 1. You measure 24 dolphins' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 13.2 ounces. Based on this, construct a 95% confidence interval for the true population mean dolphin weight. Give your answers as decimals, to two places part 2. Linda draws a heart from a standard deck of 52 cards. She returns the heart to the deck, then draws a second card. Her second card is a spade. Are...
Specifications for a part for a DVD player state that the part should weigh between 24.5 and 25.5 ounces. The process that produces the parts has a mean of 25.0 ounces and a standard deviation of 25 ounce. The distribution of output is normal. Use Table A a.What percentage of parts will not meet the weight specs? (Round your "z" value and final answer to 2 decimal places. Omit the *%" sign in your response.) Percentage of parts b. Within...
