Assume that farmers' productivity is normally distributed. Farmer-1 produces an average of 85 units of watermelon per day with a standard deviation of 20. Farmer-2 produces watermelon at an average rate of 75 per day with a standard deviation of 21. Using this information above, determine the probability that Farmer-1 will produce more watermelon than Farmer-2 in a week (5 working days). a) 0.6094 b) 0.7094 c) None of the answers are correct d) 0.6794 e) 0.7794
The pregnancy length in days for a population of new mothers can be approximated by a normal distribution with a mean of 265 days and a standard deviation of 10 days. (a) What is the minimum pregnancy length that can be in the top 11% of pregnancy lengths? (b) What is the maximum pregnancy length that can be in the bottom 4% of pregnancy lengths? (a) The minimum pregnancy length is days. (Round to one decimal place as needed.) (b) The maximum pregnancy length is (Round to one decimal place as needed.) days.
The mean height of women in a country (ages 20 - 29) is 64.2 inches. A random sample of 50 women in this age group is selected. What is the probability that the mean height for the sample is greater than 65 inches? Assume o = 2.73. The probability that the mean height for the sample is greater than 65 inches is Round to four decimal places as needed.)
In a biomedical research activity it was determined that the survival time, in weeks, of an animal when subjected to a certain exposure of gamma radiation has a gamma distribution with k = 5 and tetha = 10. a) What is the mean survival time of a randomly selected animal of the type used in the experiment? b) What is the standard deviation of survival time? c) What is the probability that an animal survives more than 30 weeks?

S. mainland in the next century (100 years)?b) What is the probability that exactly 3 such hurricanes will strike the U. S. mainland in thenext 10 years?
The area covered by 1 L of a certain stain is normally distributed with mean 10 m² and standard deviation 0.2 m². a) What is the probability that 1 L of stain will be enough to cover 10.3 m²? b) What is the probability that 2 L of stain will be enough to cover 19.9 m²?
An investigator analyzed the leading digits from 794 checks issued by seven suspect companies. The frequencies were found to be 218, 130, 106, 83, 65, 48, 48, 37, and 59, and those digits correspond to the leading digits of 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies are substantially different from the frequencies expected with Benford's law shown below, the check amounts appear to result from fraud. Use a 0.025 significance level to test for goodness-of-fit with Benford's law. Does it appear that the checks are the result of fraud?
