Expert Solution
Given that,
possible chances (x)=1
sample size(n)=44
success rate ( p )= x/n = 0.023
success probability,( po )=0.5
failure probability,( qo) = 0.5
null, Ho:p=0.5
alternate, H1: p!=0.5
level of significance, alpha = 0.05
from standard normal table, two tailed z alpha/2 =1.96
since our test is two-tailed
reject Ho, if zo < -1.96 OR if zo > 1.96
we use test statistic z proportion = p-po/sqrt(poqo/n)
zo=0.02273-0.5/(sqrt(0.25)/44)
zo =-6.332
| zo | =6.332
critical value
the value of |z alpha| at los 0.05% is 1.96
we got |zo| =6.332 & | z alpha | =1.96
make decision
hence value of | zo | > | z alpha| and here we reject Ho
p-value: two tailed ( double the one tail ) - Ha : ( p != -6.33174
) = 0
hence value of p0.05 > 0,here we reject Ho
ANSWERS
---------------
null, Ho:p=0.5
alternate, H1: p!=0.5
test statistic: -6.332
critical value: -1.96 , 1.96
decision: reject Ho
p-value: 0
we have enough evidence to support the claim that whether giving
students directed reading activities would result in higher reading
performance

a study at a dog show examined whether or not there was a
relationship between how the judges ranked dogs on their form
compared to how they ranked them on their groom. a random sample of
15 dogs were ranked from 1=best form to 15= worst form and also
ranked from 1= most groomed to 15= least groomed

a study tested whether cholesterol was reduced after using a
certain brand of margarine as part of a low fat, low cholesterol
diet. a random sample of 10 people consumed the margarine every day
and measurements of their cholesterol was taken at three time
points: before, after 4 weeks, after 8 weeks.

For the following experiment/question, pick the most appropriate
statistical test. You have the following statistical tests as
choices: some may be used more than once, others not at
all. Assume homogeneity of variance (where
applicable) and the validity of parametric tests (where
applicable), unless something is directly stated (e.g., “the data
are not at all normal”) or otherwise indicated (viz., by the
inspection of the data) which would indicate a strong and obvious
violation of an assumption. This means you must...
