Answer #1

Sample 1 | Sample 2 | |

Mean | 5.375 | 3.75 |

Variance | 4.839286 | 1.071429 |

Observations | 8 | 8 |

The test statistic:

P-value: 0.041675

Critical value:

do not reject the null hypothesis because the test statistic is less than the critical t-score

c) P-value: 0.041675

do not reject the null hypothesis because the p-value is greater than 0.01 level

d) The test statistic is not significant and failed to reject the null hypothesis. There is insufficient evidence to support that the paired means are different.

The accompanying table shows two samples that were collected as
matched pairs. Complete parts (a) through (d) below.

a. State the null and alternative hypotheses to test if the
populatio represented by Sample 1 has a higher mean than the
population represented by Sample 2. Let ud be the population mean

Test the hypothesis, using (a) the classical approach and
then (b) the P-value approach. Be sure to verify the requirements
of the test. H0: p=0.6 versus H1: p>0.6 n=200; x=140,
α=0.05
(a) Choose the correct result of the hypothesis test for the
classic approach below.
A.Do not reject the null hypothesis, because the test statistic
is greater than the critical value.
B.Do not reject the null hypothesis, because the test statistic
is less than the critical value.
C.Reject the null...

Consider the following hypothesis statement using α= 0.10 and
data from two independent samples. Assume the population variances
are equal and the populations are normally distributed. Complete
parts a and b.

Multiple Choice:
How often do you go out dancing? This question was asked
by a professional survey group on behalf of the National Arts
Survey. A random sample of 95 single men showed that 24% went out
dancing occasionally. Another random sample of 92 single women
showed that 21% went out dancing occasionally. Is the proportion of
single men who go out dancing occasionally higher than the
proportion of single women? Use a 5% level of
significance.
If men are...
