Testing: H 0 : μ ≥ 15.6 H 1 : μ < 15.6 Your sample consists of 46 values, with a sample mean of 13.4. Suppose the population standard deviation is known to be 4.47. a) Calculate the value of the test statistic, rounded to 2 decimal places. z =

The value of the test statistic is z = 3.34.

Step-by-step explanation:

The information provided is:

The test statistic is:

Thus, the value of the test statistic is z = 3.34.

the correct answer is x/3+10≥32

hope this !

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
