Question

This Question: 4 pts 2 of 42 (0 complete) Breast cancer The amount of time that it takes for various slow-growing tumors to double in size are listed in the table on the right Type of Cancer a. Find the mean and standard deviation of these data b. How many of these cancers have doubling times that are Rectal cancer within 3 standard deviations of the mean? Synovioma c. If a person had a nonspecified tumor that was doubling Skin cancer every 230 days, discuss whether this particular tumor is Lip cancer growing at a rate that would be expected Testicular cancer Esophageal cancer Doubling Time (days) 82 94 125 132 143 155 162 a. The mean of the data is days. (Round to the nearest tenth as needed.) The standard deviation of the data is days. (Round to the nearest hundredth as needed.) b. How many of the cancers have doubling times that are within 3 standard deviations of the mean? cancers have doubling times that are within 3 standard deviations of the mean. c. If a person had a nonspecified tumor that was doubling every 230 days, discuss whether this particular tumor is growing at a rate that would be expected. Choose O A. Since the doubling time of 230 days is within 3 standard deviations from the mean, this particular tumor is growing at a rate that would be expected O B. Since the doubling time of 230 days is 1 standard deviation from the mean, this particular tumor is not growing at a rate that would be expected. O c. Since the doubling time of 230 days is more than 3 standard deviations from the mean, this particular tumor is not growing at a rate that would be expected.
