Suppose you are testing the hypotheses Ho : p=0.21 vs. p +0.21 with significance level a = 0.05. A sample size of 209 results in a sample proportion of 0.26. As you know, one way to address two-sided tests is to create confidence intervals. Construct the appropriate confidence interval for p that could be used to address the test and report the upper limit of the confidence interval. Note: 1- Only round your final answer to 2 decimal places. Enter...
Assume that a sample is used to estimate a population proportion p. Find the 80% confidence interval for a sample of size 221 with 75 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 80% C.L. - Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places License Points possible: 10 This is attempt 1 of 15. Submit 10) 110) 1/10) 0/10)...
Glorious Gadgets is a retailer of astronomy equipment. They purchase equipment from a supplier and then sell it to customers in their store. The function C(x) - 3.5z + 10000 + 4000 models their total inventory costs (in dollars) as a function of the lot size for each of their orders from the supplier. The inventory costs include such things as purchasing processing, shipping, and storing the equipment. What lot size should Glorious Gadgets order to minimize their total inventory...
