KAssume that a randomly selected subject is given a bone density test. Bone density test scores are normally distributed with a mean of 0 and a standard deviation of 1: Draw a graph and find P6, the6th percentile. This is the bone density score separating the bottom 6% from the top 94%.Which graph represents P6? Choose the correct graph below.O A.P6XThe bone density score corresponding to P6 is(Round to two decimal places as needed.)OB.P6XQOUO C.AXP6SO D.AP6X

Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a distribution that is approximately normal. Use a significance level of 0.10 to test for a difference between the weights of discarded paper (in pounds) and weights of discarded plastic (in pounds). Click the icon to view the data In this example, Hg is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the weight of discarded paper minus the weight of discarded plastic for a household. What are the null and alternative hypotheses for the hypothesis test? O A. H9: Ha =0 H1: Ha 0
