Answer:
18
Step-by-step explanation:
First choose the president. From the 4 people, everyone can be the president except Dan, so there are 3 choices.
Then, choose the treasurer. Neither Bob nor Dan can be the treasurer so there are only 2 choices.
Now choose the secretary. Cyd is the only person who can't take this position, so there are 3 choices.
We are asked by the number of ways of choosing the 3 officers. Using the product rule, this is equal to 3×2×3=18.

Answer:
a: The mean of 800 customers per day
b: See below
c: z = -1.43
d: 0.0764
e: Fail to reject the null
Step-by-step explanation:
b: The hypotheses are:
H0: µ = 800
HA: µ < 800 (claim)
The mean number of daily customers was 800. She feels the number of customers has decreased, so the alternate is mu is less than 800.
c: See attached photo for the calculation of the test statistic
d: The probability is on the z table. Find the decimal that corresponds to the z-value of -1.43, which is: 0.0764
e: Since 0.0764 > 0.05, we fail to reject the null hypothesis. There is not enough evidence to support the claim that the number of customers visiting the dealership has decreased.
