Given: Karacafe is a newly launched product of Philippine Kalabaw Center. Carry, the project's head, is interested to determine the mean number of bottles of Karacafe bought his customers. From a random sample of 64 customers taken with replacement, a mean 16 bottles was computed. Suppose the number of bottles of Karacafe bought by a customer follows a normal distribution with a known standard deviation of 9. 1. The appropriate tabular value to use for the 95% confidence interval estimate of the true mean number of bottles of Karacafe bought by a customer is A. 1.960 B. 1.645 C. 2.262 D. 2.228 2. A 95% confidence interval about the mean number of bottles of Karacafe bought by a customer is A. [13.795, 18.205] B. [14.149, 17.851] C. [14.560, 17.440] D. [14.875, 17.125] 3. A 90% confidence interval about the true mean number of bottles of Karacafe bought by a customer is constructed as [16 ± 1.85]. Which of the following is(are) TRUE? 1. We are 90% confident that the true mean number of bottles of Karacafe bought by a customer is between 14.15 and 17.85 bottles. II.
