Question

Which of the following is NOT a characteristic of the t distribution? a. It is a continuous distribution. b. It has a mean of zero. c. It a symmetric distribution. d. It is similar to the z distribution when n is small. The process that produces Sonora Bars (a type of candy) is intended to produce bars with a mean weight of 56 gm. The process population standard deviation is known to be 0.77 gm. A random sample of 49 candy bars yields a mean weight of 55.82 gm. Which are the hypotheses to test whether the mean is smaller than it is supposed to be? a. H_0: mu lessthanorequalto 56, H_A: mu > 56 b. H_0: mu greaterthanorequalto 56, H_A: mu

Explanation / Answer

Will answer the first full question

18. The t is a continuous symmetric distribution with mean zero, however, it is significantly different from z distribution when n is small and only approaches z when n is large, so (d) is wrong
