Randomly selected statistics students participated in an experiment to test their ability to determine when 1 min (or 60 seconds) had passed. forty students yielded a sample mean of 58.3 sec. assume that the population standard deviation is 9.5 seconds and that there is a 95% confidence interval estimate of the population mean of all students. 55.4 sec < μ < 61.2 sec give a correct interpretation of the confidence interval. a. we are 95% confident that the interval from 55.4 seconds to 61.2 seconds actually does contain the true value of μ. b. 95% of sample means fall between 55.4 seconds and 61.2 seconds. c. there is a 95% chance that the true value of μ will fall between 55.4 seconds and 61.2 seconds. d. we are confident that 95% of values between 55.4 seconds and 61.2 seconds represent the true value of the population mean. just give a straight up answer! you!

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
