5. A particular fruit's weights are normally distributed, with a mean of 704 grams and a standard deviation of 12 grams. If you pick 12 fruit at random, what is the probability that their mean weight will be between 692 grams and 701 grams (Give answer to 4 decimal places.) 6. A particular fruit's weights are normally distributed, with a mean of 286 grams and a standard deviation of 18 grams. If you pick 25 fruit at random, what is...
4. A manufacturer knows that their items have a normally distributed lifespan, with a mean of 14.4 years, and standard deviation of 3.2 years. If you randomly purchase 21 items, what is the probability that their mean life will be longer than 15 years? (Give answer to 4 decimal places.) 5.

1) A manufacturer knows that their items have a normally distributed length, with a mean of 11.9 inches, and standard deviation of 1.4 inches. If 15 items are chosen at random, what is the probability that their mean length is less than 12.4 inches? 2) A manufacturer knows that their items have a normally distributed lifespan, with a mean of 4.2 years, and standard deviation of 0.8 years. If you randomly purchase 2 items, what is the probability that their...
A particular fruit's weights are normally distributed, with a mean of 740 grams and a standard deviation of 9 grams. If you pick 19 fruits at random, then 11% of the time, their mean weight will be greater than how many grams? Give your answer to the nearest gram.
A small business ships specialty homemade candies to anywhere in the world. Past records indicate that the weight of orders is normally distributed and the population standard deviation is 12 grams. Suppose a random sample of 16 orders is selected and each is weighed. The sample mean was found to be 110 grams with a standard deviation of 12.9 grams. Which of the following statements is true? A The sampling distribution for the sample mean follows the t-distribution with 16...
Question 3: a.) A manufacturer knows that their items have a normally distributed length, with a mean of 19.6 inches, and standard deviation of 2.4 inches. If 4 items are chosen at random, what is the probability that their mean length is less than 17.5 inches? b.) A manufacturer knows that their items have a normally distributed lifespan, with a mean of 7.5 years, and standard deviation of 0.7 years. If you randomly purchase 14 items, what is the probability...
The amount of fill (weight of contents) put into a glass jar of spaghetti sauce is normally distributed with mean ? = 841 grams and standard deviation of ? = 13 grams. (e) Find the probability that a random sample of 24 jars has a mean weight between 841 and 862 grams. (Give your answer correct to four decimal places.)
