Mathematics scores on the CBBC standardized exam are normally distributed with a population mean of 164 and a population standard deviation of 12. Ms. Norbury believes her two classes of a total of 48 students have a mathematics comprehension different than 164 and she decides to give her classes the exam. The mean on the exam was 161. Test to determine if her class' mathematics comprehension is different than 164 at the 0.05 level of significance. (Show all seven steps.)

The mean price of a cup of coffee in Portland, OR is $3.94. The owner of a new coffee house believes that the mean price of coffee is different in their neighborhood. A sample of 8 coffee prices from other local coffee shops in their area are shown below. Price 4.2 2.15 3.35 3.5 2.25 2.4 3.9 3.4 Test the claim that mean price of a cup of coffee is not equal to $3.94 using a 5% level of significance. Assume that the coffee prices are normally distributed. Give answers to at least 2 decimal places. a) Fill in the hypotheses below: H0: H1: b) The p-value is 0.0234. The correct decision is to: The correct summary would be: sufficient, insufficient or not enough evidence to reject the claim

Microsoft Word -... # The average number of accidents at controlled intersections per year is 5.4. Is this average more for intersections with cameras installed? The 47 randomly observed intersections with cameras installed had an average of 5.9 accidents per year and the standard deviation was 1.08. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: V = H₁: > 5.4 c. The test statistic t = 3.174 (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? a f. Based on this, we should g. Thus, the final conclusion is that ... 80 F3 V 5.4 Select an answer the null hypothesis. O The data suggest that the populaton mean is significantly more than 5.4 at a = 0.01, so there is statistically significant evidence to conclude that the population mean number of accidents per year at intersections with…
