The mean length of lumber is supposed to be 8.5 feet. A builder wants to check whether the shipment of lumber she receives has the correct length, so she conducts a hypothesis test. She measures 61 randomly selected pieces of lumber and finds they have a mean of 8.3 feet and standard deviation of 0.75 feet. With the help of Mathematics & R Studio: Conduct a hypothesis test to see whether she is justified to believe that the average is shorter than 8.5 feet?
Write your answers for this question on paper and then upload: From sampling 40 taxicab rides in New York City, a survey found that the mean cost of the taxi fare from the sample was $12.04. If the population standard deviation is $8.36, test the claim that the mean cost of a taxicab ride in New York City is less than $15.00. (a) State the null and alternative hypothesis. (b) By hand, find the test statistic z-score. Round to two decimal places. (c) Sketch the sampling distribution labeling the test statistic found in part (b) and compare it to the critical value z-score found in the previous question to make a decision to either reject or fail to reject the null hypothesis.

According to the College Board, scores on the math section of the SAT Reasoning college entrance test for the class of 2010 had a mean of 516 and a standard deviation of 116. Assume that they are roughly normal.One of the quartiles of the scores from the math section of the SAT Reasoning test is 438. The other quartile is _______.
NebNas manages the credit department for a grocery store chain in the province, and she would like to determine whether the mean monthly balance of credit card holders is equal to $95. A random sample of 100 accounts indicated that the mean owed is $101.5 with a sample standard deviation of $25.6. If she wanted to test whether the mean balance is different from $95 and decided to reject the null hypothesis, what will be the p-value of the test?
You are a manager of a building that hosts the local farmers market for a town. You want to investigate if the average amount of sales for a vendor per week at your building is greater than $2040. After surveying 17 of their vendors, you find that mean sales per week of the vendors sampled was $2110 with a standard deviation of $114.03. What is the value of the test statistic for your hypothesis test? Note: 1- Only round your final answer. Round your final answer to two decimal places.
A developmental psychologist studies moral awareness in adolescents. Casual observation suggests that girls develop earlier than boys although most past research contains male participants. One test of moral awareness, standardized on male teens, has a mean of 72 and standard deviation of 18. The test is administered to 58 13-year-old girls, whose mean score is 76. Test the hypothesis that females test differently from males. binomial test Kruskal-Wallace H O one-sample t one-sample z
The average starting salary of students who graduated from colleges of Business in 2009 was $48,800. A sample of 100 graduates of 2010 showed an average starting salary of $50,000.

State the null and alternative hypotheses to be tested. b. Compute the test statistic. c. The null hypothesis is to be tested at the 5% level of significance. Determine the critical value for this test. d. What do you conclude from the test? e. What does the test result mean in the context of this problem?

Answer quickly please. Need answer ASAP. A study was made to determine if the subject matter in a physics course is better understood when a lab constitutes part of the course. Students were randomly selected to participate in either a 3-semester-hour course without labs or a 4-semester-hour course with labs. In the section with labs, 17 students made an average grade of 85 with a standard deviation of 4.7, and in the section without labs, 17 students made an average grade of 79 with a standard deviation of 6.1. Construct 90% confidence interval for the difference of the mean grades between the two physics courses. Based on your interval, would you say that the laboratory course increases the average grade? Assume the populations to be approximately normally distributed.
17 dog lovers and 12 cat lovers track how much they spend on their pets each month. At the end of the month, the mean spending for cat lovers was $26.97 with a standard deviation of $14.60, and the dog lovers spending average was $18.09 with a standard deviation of $3.48. Perform an appropriate hypothesis test to test the null hypothesis that the true mean spending for dog lovers and cat lovers are equal versus the alternative that they are different. What is the test statistic and p-value of this test?
