For a hypothesis test of H0:p= 0.65 against the alternative Ha:p<0.65, the z test statistic is found to be -2.35. What can be said about his finding?
A.) The finding is significant at both a = 0.05 and a = 0.01.

B.) The finding is significant at a = 0.05, but not at a = 0.01

C.) The finding is significant at a = 0.01, but not at a = 0.05.

D.)The finding is not significant at a = 0.05 and a=0.01.

E.) The finding is inconclusive because we don't know the value of p.

Step-by-step explanation:

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
