- If the 95% confidence interval for a population mean from a certain sample is (-6.3, 4.5), then (a) the sample is mean (b) the margin of error isN1=94 X1=26 N2=78 X2=39 Confidence interval 99% ?Company A invites you to conduct a survey on its consumer satisfaction rate By surveying a few customers, you concluded that about 20 percent of consumers are satisfied with A'S service. Your acceptable interval is +1-0.05 Your confidence interval is 0.95 How many customers will you sample at least?
- you would use to create a 94% confidence interval. (5) 1. Determine the critical value (z*)If n=570 and ^p(p-hat) =0.5, construct a 99 percent confidence interval. In order to use technology, you need to compute the number of successes: x=n*p^ ________<p>________Determine the point estimate of the population mean and margin of error for the confidence interval Lower bound is 19, upper bound is 23. The point estimate of the population mean is The margin of error for the confidence interval is
- What is the positive t-value for a confidence interval for the population mean with a sample size of 30 at a 90% confidence level? Express with 3 decimalsChoose the correct option and proof the reason why you choose that one and give the evidences. A company called The Bear Necessities Business conducted a survey to gather customer feedback about a recent change they made. From the data collected, a 95% confidence interval was constructed to estimate the difference between the proportion of new customers who are positive about the change and the proportion of old customers who are positive about the change. The limits of this confidence interval are (-0.31, 0.49). Use this information to answer the following questions. The point estimate used for the confidence interval is a sample mean/sample porportion/different of two sample means/different of two sample proportion. The sample proportion for new customers was the same as/higher than/ lower than he sample proportion for old customers. Some but not all/All he sample proportion for old customers. Therefore, we can not/can claim that the proportion of customers who are…A random sample of 12 airline pilot had an average yearly income of 135000 with a standard deviation of 8000 if we want to determine a 99% confidence interval for the average yearly income what is the value of t? develop a 99% confidence interval for the average yearly income of all pilots
