Would someone please explain these problems and how to solve them. I want to understand how to do them more than I would like the answers. Thank you. Express the null hypothesis H0 and the alternative hypothesis H1 in symbolic form. Use the correct symbol ( u, p,o )for the indicated parameter. "A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO, p, is less than 4 in every one thousand." Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis. = 0.08; H1 is 3.24
