Consider the hypotheses shown below. Given that x = 110, o = 25, n = 49, a =0.01, complete parts a through c below. Ho: =116 HA:H#116 a. State the decision rule in terms of the critical value(s) of the test statistic. Reject the null hypothesis if the calculated value of the test statistic, (Round to two decimal places as needed. Use a comma to separate answers as needed.) is V the critical value(s),. Otherwise, do not reject the null hypothes b. State the calculated value of the test statistic. The test statistic is (Round to two decimal places as needed.) c. State the conclusion. Because the test statistic the null hypothesis and conclude the population mean V equal to 116.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
Please make sure to round the results to 2 decimal places.
