The weights of ripe watermelons grown at Mr. Smith’s farm are normally distributed with a standard deviation of 2.8 lb. Find the mean weight of Mr. Smith’s ripe watermelons if only 3% weigh less than 15 lb.
Answer to relevant QuestionsA machine fills containers with a mean weight per container of 16.0 oz. If no more than 5% of the containers are to weigh less than 15.8 oz, what must the standard deviation of the weights equal? (Assume normality.) a. Generate a random sample of 100 data from a normal distribution with mean 50 and standard deviation 12. b. Using the random sample of 100 data found in part a and the technology commands for calculating ordinate values on ...Draw a figure of the standard normal curve showing: a. Z(0.15) b. Z(0.82) Using Table 4B, complete the following chart of z-scores that bound a middle area of a normal distribution. Find the normal approximation for the binomial probability P(x = 4, 5), where n = 14 and p = 0.5. Compare this to the value of P(x = 4, 5) obtained from Table 2.
