(1 point) The owner of a dry cleaning store believes that the mean amount a customer spends on a dry cleaning order exceeds $22.45. A statistician has said to him that he can be statistically sure that his belief is true if the mean amount of 100 randomly chosen customer bills is greater than $23.61, or X > 23.61. It is assumed that the standard deviation in the bill amounts is $12.44 (0 = 12.44). (a) Choose the correct statistical hypotheses. O A. H. : X = 23.61, HA:X > 23.61 B. H : X = 22.45, HA:X > 22.45 c. H. :X > 23.61, HA:X 22.45 E. H: 4 > 22.45, HA: 23.61 B. Reject the null hypothesis if X > 24.5 C. Reject the null hypothesis if X > 23.9 D. Reject the null hypothesis if X > 42.91 E. Reject the null hypothesis if X > 22.45 F. Reject the null hypothesis if u > 23.9 G. Reject the null hypothesis if u > 24.5 H. Reject the null hypothesis if u > 42.91 (1 point) The owner of a dry cleaning store believes that the mean amount a customer spends on a dry cleaning order exceeds $22.45.
