Use a significance level of a=0.05 to test the claim that =19. The sample data consists of 15 scores for which x =20 and s=4.8. 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: =19 H: #19 Test statistic: t=0.8069. P-Value: P=0.2166. Accept Ho: = 19. Since P>a, there is not sufficient evidence to support the claim that the mean is different from 19. Ho =19 H #19 Test statistic: t=0.8069. P-Value: P=0.4332. Accept Ho = 19. Since P>a, there is sufficient evidence to support the claim that the mean is different from 19. Ho -19 Hu#19 Test statistic: -0.8069. P-Value: P=0.4332. Accept Ho: = 19. Since P>a, there is not sufficient evidence to support the claim that the mean is different from 19. Ho: =20 H #20 Test statistic: r=20. P-Value: P=0.4332. Accept Ho = 20. Since P>a, there is not sufficient evidence to support the claim that the mean is different from 20. Ho =19 H: p#19 O Test statistic: 1=0.8069. P-Value: P=0.4332. Rect Ho = 19. Since P>a, there is sufficient evidence to support the claim that the mean is different from 19. X G
