A driver's education course compared 1,500 students who had not taken the course with 1,850 students who had. Of those students who did not take the driver's education course, 1,150 passed the written driver's exam the first time compared with 1,440 of the students who did take the course. A significance test was conducted to determine whether there is evidence that the students who took the driver's education course were more likely to pass the written driver's exam the first time. What is the p-value for an appropriate hypothesis test?

- A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 297 people over the age of 55, 75 dream in black and white, and among 310 people under the age of 25, 19 dream in black and white. Use a 0.05 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete parts (a) through (c) below. a. Identify the test statistic. z= 6.51 (Round to two decimal places as needed.) Identify the P-value. P-value = 3.770o (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is greater than the significance level of a = 0.05, so fail to reject the null hypothesis. There is insufficient evidence to support the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. b. Test the claim by constructing an appropriate confidence…A home improvement company is interested in improving customer satisfaction rate from the 58% currently claimed. The company sponsored a survey of 273 customers and found that 171 customers were satisfied. Determine whether sufficient evidence exists that the customer satisfaction rate is different than the claim by the company.A company that produces a particular brand of juice knows that about 30% of people select that brand if given a choice of all brands. To determine if a commercial would be an effective advertising tool, the company invites 100 people to view a 30-minute program that includes a commercial for the company’s juice. After the program, the participants are offered a choice of juice brands. In this trial, 36 of the 100 participants chose the company’s juice. When a significance test was performed to determine if the true proportion of people who watch the commercial and select the company’s juice exceeds 30%, the P-value was 0.0952. At the α = 0.05 significance level, what decision should the company make? A. Because the P-value of 0.0952 > α = 0.05, the company has evidence that the true proportion of those who would select the company’s juice is larger than 30%. B. Because the P-value of 0.0952 < 0.3, the company has evidence that the true proportion of those who would select the…
