(b) Basea on your sample, graph the 90% confidence interval for the population mean of all the heights of fully grown male V • Enter the values for the lower and upper limits on the graph to show your confidence interval. • For the point (), enter the claim 7.74 from the article. 90% confidence interval: 0.000 10.000 7.740 0.000 2.000 4.000 6.000 8.000 10.000 x 5 ? (c) Does the 90% confidence interval you constructed contradict the claim made in the article? Choose the best answer from the choices below. O No, the confidence interval does not contradict the claim. The mean of 7.74 m from the article is inside the 90% confidence interval. O No, the confidence interval does not contradict the claim. The mean of 7.74 m from the article is outside the 90% confidence interval. O Yes, the confidence interval contradicts the claim. The mean of 7.74 m from the article is inside the 90% confidence interval. O Yes, the confidence interval contradicts the claim. The mean of 7.74 m from the article is outside the 90% confidence

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.
