Ford claims that its new car will average greater than 32 miles per gallon in the city. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.

Is the following statement true or false and why: If we do not reject ?0H0, then we conclude that ?1H1 is false. Washers used in a certain application are supposed to have a thickness of 2 millimeters. A quality control engineering measures the thickness for a sample of washers and tests ?0:?=2H0:μ=2 versus ?1:?≠0H1:μ≠0.    If a Type I error is made, what conclusion will be drawn regarding the mean washer thickness?

A research center claims that 26% of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of 1000 adults in that country, 29% say that they would travel into space on a commercial flight if they could afford it. At a = 0.01, is there enough evidence to reject the research center's claim? Complete parts (a) through (d) below. pu yu y w u g g w r. O C. 26 % of adults in the country would travel into space on a commercial flight if they could afford it. O D. No more than % of adults in the country would travel into space on a commercial flight if they could afford it. Let p be the population proportion of successes, where a success is an adult in the country who would travel into space on a commercial flight if they could afford it. State Ho and H Select the corect choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) B. Ho: p= 0.26 OC. Ho: p> H ps O A Ho: p+ Hp= H p*…

Please solve for p value ,determine weather to reject hypothesis and state the conclusion for enough evidence

For the situation described below, state the null and alternative hypotheses to be tested. (Enter != for ≠ as needed.) A new variety of pearl millet is expected to provide an increased yield over the variety presently in use, which has a mean yield of about 55 bushels per acre.

A company wants to reduce heat generated in their factory by chainging the oil they use.  Nominal engine temperature remains at 135 C. Data generated from experiment are shown below. Based on this data perform a T-Test to determine if engine temperature is lower that 135 C. Please indicate your null and alternative hypotheses as well as type of T test performed.  Run Temp (C) 1 130 2 132 3 133 4 128 5 136 6 129 7 131

If a treatment is expected to decrease scores in a population with µ= 30, then the alternative hypothesis is µ ≤ 30.  True or false?
