4) - \(\mu\) is the population mean under the null hypothesis (50) - \(\sigma\) is the population standard deviation (4.1) - \(n\) is the sample size (100) Plugging in the values, we get: \[ z = \frac{49.4 - 50}{\frac{4.1}{\sqrt{100}}} = \frac{-0.6}{0.41} = -1.46 Show more…

A hypothesis test is being performed based on a random sample of size 41 with null hypothesis µ=650 and alternative hypothesis µ<650. The sample yielded a mean of 623.6 and a standard deviation of 76.4. Find the value of the test statistic. Use the t-table to estimate the P-value associated with this situation.

In a test of the hypothesis H0 : μ = 50 versus Ha : μ > 50, a sample of n = 100 observations possessed mean x̄ = 50.2 and standard deviation s = 4.3. Find and interpret the p-value for this test. Using α = 0.05.
