- Would you expect the F-ratio of an independent-samples ANOVA using the same data to be the same, higher than, or lower than the F-ratio of a repeated measures ANOVA?Suppose that a manufacturer of laptop batteries claims that his product last more than 950 hours. They test 45 batteries and found a sample mean of 925 hours and the population standard deviation of 55 hours. Use 5% significance level. Should the claim be accepted?Find the critical value for a test for correlation with α = 0.05 for a sample size of 21.
- Based on a suitable statistic, find out the counter with more consistentperformance.If there is an overall significant F in a one way ANOVA, can we conclude that the group membership or treatment variable caused the observed differences in the group means? Why or Why not?A cellular telephone manufacturer that entered the post-regulation market quickly has an initial problem with excessive customer complaints and consequent returns of cell phones for repair or replacement. The manufacturer wants to estimate the magnitude of the problem in order to design a quality control program. How many cellular telephones should be sampled and checked in order to estimate the proportion that is defective to within 1% with 90% confidence?

True or False?Which variable pair (in part a or b or c) has a stronger association according to the comparison of the correlations and which variable pair has a stronger association according to the comparison of the p-values? Does the comparisons according to correlation coefficients and p-values agree on which variable pair indicate the same stronger association? If not, why is there such a discrepancy? Which gene pair (in part a or b or c) has a stronger association do you think according to the scatter plots? Part A: Pearson correlation of rb: 0.380875 P-value of pb: 0.0000 Significance level: α = 0.05 So, there is statistically significant association at α = 0.5 between the genes. Also, since the p-value is less than 0.05, the null hypothesis is rejected. Furthermore, the magnitude and direction are that of a positive correlation between the provided genes. Part B: Pearson correlation of rb: 0.380875 P-value of pb: 0.0000 Significance level: α = 0.05 So, there is statistically significant…
