Which of the following expressions for the null H, and alternative H, hypothesis is correct. OH : u = 45; H, :p + 45 OH :u < 45; H, :p > 45 OH :u= 45; H, :p < 45 OH :p> 45; H: 4 < 45 Ho : u + 45; Hq :u= 45

Answer 1

The hypothesis will Here, the claim Frue mean temperature in incorrect" needed to be tested (The claim is wrong. The null and alternative hypothesin are: Ho: M = 45 Hair&45 i. Option
