State the null and alternative hypotheses to test if a difference in means exists between the populations represented by Samples 1 and 2. Let mud be the population mean of? matched-pair differences for Sample 1 minus Sample 2. Choose the correct answer below. B.

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.

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...
