Suppose we have a set of paired data, and let d=xafter−xbefore . The null hypothesis is H0:μd=0, the alternative hypothesis is Ha:μd≠0, and the population standard deviation σ is not known. Jordan collects a sample of size n=9 and computes d¯=2.2 and sd=3.3What is the value of the test statistic?The probability of obtaining a test statistic greater than Jordan's test statistic is 0.0403. Use this probability to determine the P-value for Jordan's hypothesis test. (Round to three decimal places.)

Needmax 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.
