← A data set includes times (in minutes) of taxi cab rides in New York City yellow cabs during a Friday morning of the same day in a recent year. Using 33 of the times to test the claim that the mean of all such times is less than 15 minutes, the accompanying Minitab display is obtained. Test the given claim by using the display provided from Minitab. Use a 0.10 significance level. ⑪Click the icon to view the Minitab display. Identify the null and alternative hypotheses. Ho H₁: (Type integers or decimals. Do not round.) Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. the null hypothesis. There sufficient evidence at the 0.10 significance level to City yellow cabs during the Friday morning is less than 15 minutes. the claim that the mean time of all taxi cab rides in New York

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

Please do not give solution in image formate thanku.  A school psychologist wants to determine if reprimanding in public (in front of the class) or private is more effective for curbing behavior. He randomly selects 12 students whose teachers reprimand in private and 12 students whose teachers reprimand in public. At the end of the year he determines the number of misbehaviors for each student. For the public condition and mean=7.7 and s=4.1 for the private condition mean=4.2 and s=3.5. Which method is more effective? What is the percentage of variance accounted for by the method of reprimand? What is the power of your test?

The first pic is the question. Since some tutors have been solving the problems wrong recently (no judgment), I’ve added a sample question to solve problem.

d.     Interpret the value of IQR in the above table.

What is a Type I error in this​ problem?     A. A Type I error would be to conclude that the true mean level of support for sustainability is not 66 ​when, in​ fact, the mean is equal to 66.   B. A Type I error would be to conclude that the sample mean level of support for sustainability is greater than 66 ​when, in​ fact, the sample mean is less than 66.   C. A Type I error would be to conclude that the true mean level of support for sustainability is 66 ​when, in​ fact, the mean is not equal to 66.   D. A Type I error would be to conclude that the sample mean level of support for sustainability is less than 66 ​when, in​ fact, the sample mean is greater than 66.
