The height of adult males from a specific species is normally distributed with an unknown mean a and unknown variance a. We took a sample of 2 16 adult males finding the sample mean 2.3 meters and sample slandard deviation s 0.4 melers. (b) A scientific group claims that the true population mean height a is more than 2 meters. 6l What is the form of the null and alternative hypotheses for testing group's claim? OINO answer given O(1) Ho : JA = 2, VS HA: 4> 2.
