we hat is the measure of ABC Is15
Let's start with the question, how many questions do you need to get 88%?
so were are looking for
?/25 = 88% and 88% is also 0.88 so we can multiply 25 by 0.88
we get 22
But this doesn't here. the question asks us how many mistakes do you need. you can just subtract 22 from 25
25-22= 3
you need 3 misses to get 88%
Answer:
b.0.02
Step-by-step explanation:
As he defined the significance level in α=0.05, and this is a one-side test (as the claim is that the percentage is <em>higher, </em>not lower), any P-value below the significance level shows a significant effect and gives evidence to reject the null hypothesis.
The P-value represents the probability of having this sample statistic, given that the statement of the null hypothesis is true. Then, the lower the P-value, more evident is that the null hypothesis is not correct. This threshold value to reject (or not) the null hypothesis is the significance level.
a) As the significance level is 0.05, a P-value=0.07 would not be low enough to reject the null hypothesis.
c) The magnitude of a P-value has impact on whether he rejects or fails to reject the null hypothesis, as is the value that is compared to the significance level to reject or not the null hypothesis.
