Alternative Hypothesis: H1: The proportion of stocks that went up is significantly less than 0.3. Consider, the sample proportion is, p^=xn=1867=0.2687 Test statistic: z=p^-pp(1-p)n =0.2687-0.30.3(1-0.3)67 =-0.559 p value: p=P(z<test statistic) =P(z<-0.559) =0.2881 Decision Rule: If p-value ≤ α, then reject the null hypothesis. Conclusion: The level of significance is α=0.02 Here, the p-value is greater than the level of significance. From the decision rule, failed to reject the null hypothesis. Correct option:

Many investors and financial analysts believe the
Dow Jones Industrial Average (DJIA) gives a good
barometer of the overall stock market. On January
31, 2006, 9 of the 30 stocks making up the DJIA
increased in price (The Wall Street Journal, February

2b. It is thought that 20% of Annual Tax returns to the Australian Tax Office (ATO) contain errors of one kind or another. An auditor in the ATO investigating the number of returns with errors in a particular industry takes a sample of 25 returns and classifies each return as being “in error” or “not in error”. i. If the variable X is used to represent the number of returns in the sample that are in error, and assuming this industry is no different to other industries in terms of the error rate, then state:• the values that X may take;• the distribution of this variable; and • the parameter/s of this distribution. ii. Determine the probability that 6 or less returns in this sample are in error. The auditor found that there were 13 tax returns with errors in this sample. iii.

Members of the city council want to know if a majority of city residents supports a 1% increase in the sales tax to fund road repairs. To investigate, they survey a random sample of 300 city residents and use the results to test the following hypotheses: Ho p = 0.50 H p> 0.50 where p is the proportion of all city residents who support a 1% increase in the sales tax to fund road repairs. Given that P-value = 0.18, which of the following would be the most appropriate conclusion? Because the P-value is large, we reject Ho. We have convincing evidence that at most 50% of city residents support the tax increase. Because the P-value is large, we fail to reject Ho. We have convincing evidence that more than 50% of cit residents support the tax increase, Because the P-value is large, we reject Ho.

Indicate whether the following statements are true, false, or uncertain, and provide a short (no more than three sentences) justification of your response. 1. Consider a setting where two researchers are trying to estimate the relation between a specific variable of interest x and an outcome variable y. While the first researcher (we shall call her A) has been very careful in the measurement of y, the second one (researcher B) has had problems with data entry, which resulted in the outcome being observed with a substantial amount of measurement error. As long as the measurement error is independent of x, we expect the range of estimates the two researchers will get to be the same.

The Admission director for a college far from mart and town believes that an inverse relationship exists between a private college's average discount rate(determined by the average amount of scholarships students receive) and the annual yield (the percentage of admitted students who actually attend). The Director's independent variable is a private college's discount rate measured as a percentage, and the dependent variable is the college's annual yield measured as a percentage. The following results were obtained for a sample of 30 private colleges: x- Discount rate(percentage) - range: 35 to 72 percent y- Annual Yield(percentage) - range: 12 o 81 percent Σxi = 1612 Σyi = 898 Σxiyi = 44,377 Σxi2 = 89,790 Σyi2 = 35,704 a.
