Lets be a random variable representing dividend yield of Australian bank stocks. We may assume that x has a normal distribution with o-2.6%. A random sample of 17 Auxaralian bankstocks has a sample mean of x 8.76%. For the entire Australian stock market, the mean dividend yield is -6.5%. Do these data indicate that the dividend yield of all Australian benkstocks is higher than 6.5%? Use a-0.01. Are the data statistically significant at the given level of significance? Based on your answers, will you reject or fail to reject the null hypoterThe P-value is less than than the level of significance and so the data are not statistically significant. Thus, we reject the null hypothesisThe P-value is less than than the level of significance and so the data are statistically significant. Thus, we fail to reject the null hypothesisThe P-value is greater than than the level of significance and so the data are statistically significant. Thus, we reject the null bypothesisThe P-value is greater than than the level of significance and so the data are not statistically significant. Thus, we fail to reject the null hypothesisThe P-value is less than than the level of significance and so the data are statistically significant. Thus, we reject the null hypothesis

During my office hours (from 12pm to 6 pm), an average of about 1 student per hour comes in for help. Assuming that the probability of a student coming in is uniform throughout my office hours, what are the odds that on a particular day I would have 6 students come in for help? What is the mean number of students that will come see me on a particular day? Variance? Standard deviation?
18. On average, a banana will last 6.3 days from the time it is purchased in the store to the time it is too rotten to eat. Is the mean time to spoil greater if the banana is hung from the ceiling? The data show results of an experiment with 15 bananas that are hung from the ceiling. Assume that that distribution of the population is normal. 5.4, 8.2, 7.8, 6.8, 6.4, 8.3, 5, 7.5, 7, 5.3, 6.9, 8.8, 8.9, 9, 8.5 What can be concluded at the the αα = 0.05 level of significance level of significance? For this study, we should use T- Test, Z test The null and alternative hypotheses would be: H0: P or U, <>=, H1: P or U, <>=, The test statistic T,Z = (please show your answer to 3 decimal places.)

O As part of his workout routine, Jim swim's 50m several times per session. His times follow a normal distribution with a mean of 45 seconds with a standard deviation of 1.8 seconds. What percent of his times would he expect to be between 42 and 48 seconds?
high school students across the nation compete in a financial capability each year by taking a national financial capability challenge exam. students who score in the top 23 percent are recognized publicly for their achievement by the department of the treasury. assuming a normal distribution, how many standard deviations above the mean does a student have to score to be publicly recognized
Scenario: The mean score for all high school seniors taking a college entrance exam is 500. Advocates for a charter school boast that their program helps to increase student exam scores. For a random sample of 100 students from the charter school, the mean exam score is 516 with a standard deviation of 90. Test the school's claim that their program improves student test scores. Question: Is the charter school correct in their claim? In a short paragraph, formulate the correct conclusions for this test given the results above. In your answer, make sure to address both the null and alternative hypotheses, as well as the charter school's claim.
