A simple random sample of the sitting heights of 36 male students has a mean of 92.8cm. The population of males has sitting heights with a mean of 91.4 cm and a standard deviation of 3.6 cm. Using a 0.05 significance level to test the claim, the p-value of 0.0198 is found. What is the final conclusion about testing the claim that male students have a sitting height different from 91.4 cm. Could anyone show me how to do this?

The square pyramid has a volume of 441 cubic inches. what is the value of x? 1/7x is the height x is the base

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
