21. Gardeners at KSA Organic Gardening Center, have a strict method of producing the finest tomatoes. If the method used produces tomatoes with a mean weight of 4 ounces and a standard deviation of 0.21 ounces, find the Z score that represents a tomato weighing 4.5 ounces. a. 2.38 b. - 0.21 c. - 2.38 d. 0.50

Step 1
The Z score is a statistical measurement that describes a value's relationship to the mean of a group of values, measured in terms of standard deviations from the mean. The formula to calculate the Z score is: \[ Z = \frac{(X - \mu)}{\sigma} \] where \( X \) is Show more…

The weight (W) of tomatoes grown by a farmer follows a normal distribution. W is measured in grams. The normal distribution curve of W is shown below. 0 20 40 60 80 100 120 140 160 180 200 220 240 Weight of tomatoes, grams (W) (a) Write down the mean weight of tomatoes. The standard deviation of the weights of tomatoes is 30 grams. (b) The farmer sorts the tomatoes before selling. He chooses to group Medium sized tomatoes, with a weight in the range of 100 ≤ W ≤ 150. Estimate the percentage of tomatoes that are classified as Medium. (c) The farmer produces tomato juice from the Small sized tomatoes, weights: W ≤ A. Find the value of A if 10% of all tomatoes are used for juice production. Give your answer correct to two decimal places.

A vegetable distributor knows that during the month of August, the weights of its tomatoes are normally distributed with a mean of 0.63 lb and a standard deviation of 0.15 lb. (See Example 2 in this section.) (a) What percent of the tomatoes weigh less than 0.78 lb? % (b) In a shipment of 8,000 tomatoes, how many tomatoes can be expected to weigh more than 0.33 lb? tomatoes (c) In a shipment of 3,500 tomatoes, how many tomatoes can be expected to weigh from 0.33 lb to 0.93 lb? tomatoes

Assume the given distributions are approximately normal. Cucumbers grown on a certain farm have weights with a standard deviation of 2 ounces. What is the mean weight if $85 \%$ of the cucumbers weigh less than 16 ounces? (A) $16-0.518$ (B) $16-0.85(2)$ (C) $16-1.036(2)$ (D) $16+0.85(2)$ (E) $16+1.036(2)$
