In order to suport the claim made by the teaching professional, what null and tomative hypotheses should you to M $1,800 HP $1,800 Suppose you select a = 0.01. Interpret the value in the words of the problem The probably that the null hypothesis is when the average gain $1,800 s 0.01 c. For -0.01, specify the rejection region of a large-sample test. Choose the correct answer below. OA 2-1.545 OC-1645<241.645 OL z> 1545 OG <-230 OB-2.575<2.575 OD 22.33 OF 24-1645 or 2 1 545 OHZ< -2.575 orz>2.575

Answer 1

a)

null hypothesis:Ho μ		=	1800
Alternate Hypothesis:Ha μ		≠	1800

b)

the probability that the null hypothesis is rejected when the average gain is $1800 is 0.01

c)

option H is correct : z<-2.575 or z>2.575
