Suppose the coffee industry claimed that the average adult drinks 1.7 cups of coffee per day. to test this claim, a random sample of 40 adults was selected, and their average coffee consumption was found to be 1.85 cups per day. assume the standard deviation of daily coffee consumption per day is 0.6 cups. using alphaequals0.05, complete parts a and b below.
a. is the coffee industry's claim supported by this sample?
determine the null and alternative hypotheses.
upper h0:
upper h1:
the z-test statistic is
(round to two decimal places as needed.)
the critical z-score(s) is(are)
(round to two decimal places as needed. use a comma to separate answers as needed.)
b. determine the p-value for this test.
the p-value is
(round to three decimal places as needed.)

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
