When the population variance is unknown and must be inferred from the sample, the standard approach for assessing a mean uses the t-distribution rather than the normal z-distribution. This is because we replace the true standard deviation with the samp......Login to view full explanation

The critical value t 𝛼 2 ,k is the (1- 𝛼 /2) - quantile for a t distribution with k degrees of freedom.  Compute  t 𝛼 2 ,k when   𝛼 = .02 and k = 17

The student academic group on a college campus claims that second-year students study around 2.7 hours per day, on average. However, one Introduction to Statistics class at Emory believed that the average would be significantly greater than 2.7 hours per day, so they took a random sample of 28 second-year students and performed a two-sided hypothesis test. At 𝛼 = 0.01, which of the following represents the smallest test statistic required to reject the null hypothesis? You must use the t-table to answer this question. Also, treat the test statistic as is; Do NOT round up or down the numbers below.

Which of the following is true regarding the t-distribution?

A scientist is investigating the average rate of enzyme activity in a species of freshwater algae under controlled lab conditions. The rate of activity is known to follow a Normal distribution in the population. The scientist randomly selects a sample of n = 9 algae specimens. They calculate point estimates for the mean enzyme activity rate and the standard deviation of the population based on the sample. They then estimate the standard error of the sample mean enzyme activity rate. Assuming this sampling method is used in future experiments, what is the probability that the sample mean enzyme activity rate will fall within .6 estimated standard errors of the true population mean?
