You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly larger than 73% at a level of significance of α= 0.05. According to your sample, 56 out of 70 potential voters prefer the Democratic candidate. a. The test statistic= (please show your answer to 3 decimal places.) b. The p-value = (Please show your answer to 4 decimal places.)
Score: 90/260 • Question 11 Suppose your manager indicates that for a normally distributed data set you are analyzing, your company wants data points between z = -1.6 and z = 1.6 standard deviations of the mean (or within 1,6 standard deviations of the mean). What percent of the data points will fall in that range? Answer: percent (Enter a number between 0 and 100, not 0 and 1 and round to 2 decimal places)

Only 19% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 339 randomly selected registered voters surveyed, 75 of them will vote in the upcoming election. What can be concluded at the αα = 0.05 level of significance? The p-value = (Please show your answer to 4 decimal places.) The p-value is ? ≤ > αα Based on this, we should Select an answer reject accept fail to reject the null hypothesis. Thus, the final conclusion is that ... A) The data suggest the population proportion is not significantly higher than 19% at αα = 0.05, so there is statistically insignificant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be higher than 19%. B) The data suggest the population proportion is not significantly higher than 19% at αα = 0.05, so there is statistically significant evidence to conclude that the percentage of registered voters who will vote in the…

Stoaches are fictional creatures, sometimes mistaken for mome raths. Suppose a two-tailed t-test is conducted to test for a difference between the population means of adult female stoach weights and adult male stoach weights. The female sample has 13 weights, and the male sample has 7 weights. The t-statistic for the test is -0.20542. What is the p-value? (Give your answer to 4 decimal places.) p-value:

How would you report the results? The derived t = 0.02 was not significant at p = .05 with df = 10. Therefore, Ho was not rejected, and it was concluded that the mean pretest score for students at the beginning of the semester (18.27) was not different than the mean posttest score for students at the end of the semester (22.00), t(10) -= 0.02, p .05. In terms of the research question, it appears that the curriculum was not effective in promoting learning.
