7s + 20 = 4s -13
7s - 4s = -13 -20
3s = -33
s = -33/3
s = -11
Answer:
a. We do not have enough evidence to conclude that the two means differ.
b. There is no difference in the population means.
Step-by-step explanation:
a) Results of the test:
Having p - value to be very high, we have strong evidence of not rejecting H o and hence,
We do not have enough evidence to conclude that the two means differ.
b) For a one tailed test,
p - value = 0.115/2 = 0.0575
Interpretation: p - value is the probability of getting the difference as small as obtained in the sample, given that the null hypothesis is true i.e. there is no difference in the population means.
the answer is 12 because if you look at the position of the y axis when x equals 2 then look at the y value when x equals 4 you will get the 2 numbers 4 and 16 now subtract 16 by 4 and you get 12.
C) 2/3 of a page per hour
Since he can write 1/3 of a page in 1/2 of an hour, multiply by 2 to find that he writes 2/3 of a page in 1 hour.
