The standard deviation of the volumes of blood draws in purple-top tubes is known to be approximately 4 milliliters ( mls ). Later, in problem # 4 , we will wish to construct a 95% confidence interval for the mean volume of blood draws in purple top tubes. The volumes of 75 blood draws in purple-top tubes are determined. The sample mean volume is 6 ml. The sample standard deviation is 2.5 ml. Identify the following:
a. x=
b. Ï =
c. n =
Determine the correct distribution for problem.

step-by-step explanation:

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.
