A researcher hypothesizes that the general population has a mean of u = 50 on some variable of interest. To test this hypothesis, the researcher collects data from a sample of n = 16 participants. The sample mean is then calculated to be M = 55 with sample standard deviation of s = 3. Using a two-tailed hypothesis test with a = .05, which of the following lists the correct values of a 95% confidence interval? 23.40 to 52.60 2.13 to 1.60 53.40 to 56.60 54.99 to 58.60

Question
A researcher hypothesizes that the general population has a mean of u = 50 on some variable of interest. To test this hypothesis, the researcher collects data from a sample of n = 16 participants. The sample mean is then calculated to be M = 55 with sample %3D standard deviation of s = 3. Using a two-tailed hypothesis test with a = .05, which of the following lists the correct values of a 95% confidence interval? 23.40 to 52.60 2.13 to 1.60 O 53.40 to 56.60 54.99 to 58.60
