Refer to the Lincolnville School District bus data 2015.

  1. Conduct a test of hypothesis to reveal whether the mean maintenance cost is equal for each of the bus manufacturers. Use the .01 significance level.
  2. Conduct a test of hypothesis to determine whether the mean miles traveled since the last maintenance is equal for each bus manufacturer. Use the .05 significance level.

Conduct a test of the hypothesis that the mean climate sentiment score is different than 33.8 (the climate sentiment score from last quarter’s Stat 220). Be sure to state your statistical hypotheses using symbols, report the p-value, report the decision of your test, and provide a conclusion in the context of the problem. Use a 5% significance level. z=2.9389 p-value=0.003294 Alternative hypothesis: the true mean not equal to 33.8 For a 95% confidence interval: 34.15060 to 35.55453 Sample estimates: mean...

1. A random sample of 64 second graders in a certain school district are given a standardized mathematics skills test. The sample mean score is 51.93. Assume the standard deviation for the population of test scores is 15. The nationwide average score on this test is 50. The school superintendent wants to know whether the second graders in her school district have greater math skills than the nationwide average. Perform the hypothesis test and compute the P value. Based on...

Gail is a student in a class that has been asked to conduct a hypothesis test for a population proportion. The null and alternative hypotheses are: H0: p = 0.4 Ha: p ≠ 0.4 Gail is given a sample and calculates the test statistic. Using a level of significance of α = 0.05, she does not reject the null hypothesis. Gail's friends, Andrew and Ben, also use the sample to calculate a test statistic. However, they differ in the level...
