Poverty in Alaska vs Hawaii. If we have 26 out of 350 families in Hawaii that were below the poverty time, and if we random select 300 Alaska families, we find 35 families below the poverty line. At the 1% significance level, do the data provide sufficient evidence to conclude a difference in the proportion of families below the poverty line for Alaska and Hawaii? Based on the hypotheses, find the following:Test Statistic = _____________p-value = ______________ Find a 99% confidence interval for the difference in proportion of families below the poverty line in Alaska and Hawaii. ______≤ p1 - p2 ≤ ___________
Report an appropriate hypothesis test for a positive linear relationship and use a 5% significance level. Explain the potential error in words, in context. In the answer options below I have used the phrase “a certain relationship” because I don’t want to give away exactly what type of relationship it is. Group of answer choices We would be accepting that there was a certain relationship between Sale amount and Tip when actually there wasn’t. We would not be accepting that there was a certain relationship between Sale amount and Tip when indeed there wasn’t. We would not be accepting that there was a certain relationship between Sale amount and Tip when actually there was. We would be accepting that there was a certain relationship between Sale amount and Tip when indeed there was.
Which of the following statements about the False Discovery Rate (FDR) is correct? The FDR is the only method available for controlling multiple testing error in transcriptional profiling data The FDR cutoff value should be held to the same standard as the p-value cutoff when doing hypothesis testing The FDR can be interpreted as meaning “the proportion of the significant gene list one would expect to find significant by chance due to the multiple testing error” The FDR greatly simplifies analysis, allowing researchers to add many more treatment groups to their experimental designs Its best to save your signal intensity data before calculating the FDR, as the FDR calculation will change the signal values for all of your data

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1413 referee calls, with the result that 426 of the calls were overturned. Women challenged 742 referee calls, and 228 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Identify the test statistic. z= ? (Round to two decimal places as needed.) Part 3 Identify the P-value. P-value= ? (Round to three decimal places as needed.) Part 4 What is the conclusion based on the hypothesis test? The P-value is ▼ greater than or less than the significance level of α=0.05, so ▼ fail to reject or reject the null hypothesis. There ▼ is not sufficient or is sufficient evidence to warrant rejection of the claim that women and men have equal success in challenging calls. Part 5 b. Test the claim by constructing an appropriate confidence interval. The 95% confidence…
