(b) If a sample of 10 cups of ice cream is selected, what is the probability that the mean of the sample will be larger than 670 mg?

The quality control manager at a computer manufacturing company believes that the mean life of a computer is 120 months, with a variance of 100. If he is correct, what is the probability that the mean of a sample of 57 computers would differ from the population mean by less than 0.9 months? Round your answer to four decimal places.

What is the Discrete Variance when sample size is 82 with a probability of 0.82?

The cost of 5 gallons of ice cream has a variance of 36 with a mean of 35 dollars during the summer. What is the probability that the sample mean would be less than  33.8 dollars if a sample of 96 5-gallon pails is randomly selected? Round your answer to four decimal places.

Suppose you did an experiment with 3 groups and 16 subjects per group. The sample variances in the three groups were 14, 16, and 18. Using Tukey's test to compare the means, what would be the two-tailed probability for a comparison of the first mean (14) with the last mean (18)?

A random variable follows a binomial distribution with a probability of success equal to 0.68. For a sample size of n=8, find:- 1.The probability of exactly 3 success 2.The expected value(mean) 3.The variance of the random variable
