Upper H 0 : sigma equals 4.6

To test Ho: o =4.6 versus H,: 0 4.6, a random sample of size n = 14 is obtained from a population that is known to be normally distributed.
(a) If the sample standard deviation is determined to be s = 5.3, compute the test statistic.
(b) If the researcher decides to test this hypothesis at the a = 0.01 level of significance, use technology to determine the P-value.
(c) Will the researcher reject the null hypothesis?
(a) The test statistic is x6 =
(Round to two decimal places as needed.)
(b) The P-value is
(Round to three decimal places as needed.)
(c) Since the P-value is
than the level of significance, the researcher
reject the null hypothesis H,: o = 4.6.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
