Answer:
Step-by-step explanation:
First you need to do 5x5=25
Answer:
5v24
Step-by-step explanation:
(v22)(5v2) = 5v(2+22) = 5v24
A. Nancy has the greatest spread because her longest training time was 105 and her shortest being 82, making the spread 23, and Peter’s spread is only... Longest: 112 Shortest: 92 making it 20!
b. Nancy. Middle %50 would be Peter’s 110-92 making the spread 18, and Nancy’s spread is 93-90 making the spread making it 12
c. The spreads tell us they are very close to each other, and just Peter has more time but a less spread than Nancy.
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.
Answer:
2x=5 x=2.5
Step-by-step explanation:
2x+5=10
2x=10-5
