a. Compute the p-value for this test. (Round to four decimal A. p-value = NORM.S.DIST(-2.13,1) = 0.0166 B. p-value = 2"(1-NORM.S.DIST(-2.13,1)) = 1.9668 OC. p-value = 2*NORM.S.DIST(-2.13,1) = 0.0332 O D. p-value = 1-NORM.S.DIST(-2.13,1) = 0.9834 b. What is the statistical decision?
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.
![In a one-tail hypothesis test where you reject H, only in the lower tail, the ZSTAT = - 2.13 , what is the statistical decision if the null hypothesis is tested at the 0.05 level of significance?
a. Compute the p-value for this test. (Round to four decimal places to the right of the decimal point as needed.)
O A. p-value = NORM.S.DIST(-2.13,1) = 0.0166
O B. p-value = 2*(1-NORM.S.DIST(-2.13,1)) = 1.9668
OC. p-value = 2*NORM.S.DIST(-2.13,1) = 0.0332
O D. p-value = 1-NORM.S.DIST(-2.13,1) = 0.9834
b. What is the statistical decision?
O A. Since the p-value is less than a = 0.05, do not reject Ho
O B. Since the p-value is greater than a = 0.05, do not reject Ho
OC. Since the p-value is greater than a = 0.05, reject H,
O D. Since the p-value is less than a = 0.05, reject H,](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fafc75c11-f74c-4700-aac3-dcc346278078%2Fafce68ab-2062-4245-a983-48157066e6bf%2Fb6bvqdf_processed.png&w=3840&q=75)
