1. Consider the following test of whether the coin is fair. Toss a coin three times, if the coin lands whether all heads or tails, reject the Ho: p=1/2. If P=4/5, What is the probability of type II error for this procedure?
2. A sample of 350 orders for takeout at a local pizzeria found out that the average cost of order was $22 with s=$14. Find the error of margin if we use 95% confidence interval for average cost per order.© BrainMass Inc. brainmass.com June 4, 2020, 5:08 am ad1c9bdddf
1. Let X be number of heads after three tosses. So X has a binomial distribution with n=3 and p is to be ...
The solution gives detailed steps on finding the probability of type II error and the error of margin if we use 95% confidence interval.
