Question

Use a significance level of a=0.05 to test the claim that u = 20.0. The sample data consists of 10 scores for which x =20.5 ands=4.5. State the null and
alternative hypotheses, compute the value of the test statistic, and find the P-value for the sample. State your conclusions about the claim.
Ho:=20.0
H: p 20.0
O Test statistic: t=0.3514. P-Value: P= 0.7334. Accept H, : µ = 20.0.
Since P>a, thère is not sufficient evidence to support the claim that the mean is
different from 20.0.
H:p=20.0
H,: p 20.0
O Test statistic: t=0.3514. P-Value: P 0.7334. Reject H: = 20.0.
Since P>a, there is sufficient evidence to support the claim that the mean is different
from 20.0.
Ho: H=20.0
H : p= 20.0
O Test statistic: t=0.3514. P-Value: P= 0.3667. Accept H:H = 20.0.
Since P>a, there is not sufficient evidence to support the claim that the mean is
different from 20.0.
H: p= 20.5
H,:u 20.5

Suppose that at a particular college, a random sample found that 25 out of 100 students who use the internet use Twitter. Does this provide evidence that the true proportion of students at this college who use Twitter is higher than the nationally stated 15%? Use a significance level of 0.05 and the p-value to give your decision. The correct hypotheses to use are: Ho: p = 0.15 HA: p > 0.15 Blank #1: Report the test statistic to two decimal places Blank #2: Report the p-value to four decimal places. Blank #3: Give the test decision: (reject or do not reject) Ho Blank #4: Evidence _[favors or does not favor) that the true proportion of students at this college who use Twitter is higher than the nationally stated 15%.
