ID: A 6. The proportion of pepperoni pizza orders on a randomly selected day at a local pizza shop is approximately normal with mean 0.25 and standard deviation 0.02. Let X = the proportion of pepperoni pizza orders on a randomly selected day. (a) Carefully sketch a normal curve for this situation. Be sure to label the mean and one, two, and three standard deviations on each side of the mean. Use the 68-95-99.7 rule to approximate: (b) P(X > 0.29) I. (c) The probability that the proportion of pepperoni pizza orders is between 0.21 and 0.27. Use Table A to answer the following:

Use the 68-95-99.7 rule to approximate: (b) P(X > 0.29) (c) The probability that the proportion of pepperoni pizza orders is between 0.21 and 0.27. Use Table A to answer the following: (d) What is the probability that the proportion of pepperoni pizza orders is between 0.24 and 0.28? (e) What is the probability that the proportion of pepperoni pizza orders is greater than 0.30? 7. For this question, use the 68-95-99.7 rule. A researcher has a colony of bongo spiders in his lab.. There are 1200 adult spiders in the colony, and their weights are normally distributed with a mean of 11 grams and a standard deviation of 2 grams. (a) Sketch a normal curve and label the axis using the mean and standard deviation. Be sure to label one, two, and three standard deviations on either side of the mean. (b) Using the 68-95-99.7 rule, about what percent of spiders in the colony weigh between 7 grams and 13 grams?
