Building codes in southern Florida require hurricane straps on single-family dwellings in order to more securely anchor the roof to the buildings. The straps should have no more than a 10% chance of failure in 150mph wind, and no more than a 45% chance of failure in a 200mph wind. 164 straps are tested at 200mph, and 48 of them fail. (a) Perform a hypothesis test to evaluate the claim that the straps are performing to code to an α = 0.01 (b) Provide the p − value for your test statistic determined in (a) (c) If you wished to construct a 95% confidence interval for the population proportion with half-width E = 0.01, approximately how many straps would you need to test

If a researcher were conducting a two-tailed/non-directional hypothesis test with an alpha of 0.10 and a sample of size n=120, what would the Zcrit value be?
The NAEP considers that a national average of 283 is an acceptable performance. Using α = .05, run a two-tail t-test for one sample to test Ho: µ=283 for the 2019 scores. Report the t-obt, df, and p-values. Would you reject the null hypothesis that the 2019 scores come from a population with average 283? If this is the case, does it come from a population from larger or smaller average?
A public research company says that 63% of U.S. adults are concerned about their jobs because of the current state of the economy. A social services group surveys 500 adults and has a result of 70%. Using an alpha of.05 test the hypothesis claim of 63%
A researcher did a one-tailed one-sample t-test to test the hypothesis that babies prefer the color blue over the color red. He collected a sample of 26 babies and presented them with a red plastic star and a blue plastic start for 12 seconds. The researcher measured the amount of time each baby spent watching the blue star out of the 12 seconds. What is µ based on the null hypothesis?
31% of all pygmy softshell tortoises have stripes on their shells. A herpetologist in Cititon collects a sample of 28 pygmy softshell tortoises and finds that 8 of them have stripes on their shells. Is there enough evidence to conclude, at a significance of alpha = 0.05, that the proportion of pygmy softshell tortoises in Cititon with stripes on their shells is less than 31%? What is the claim? What is the null hypothesis? What is the alternative hypothesis? What is the test statistic? What is/are the critical value(s)? Do we reject the null hypothesis? What conclusion do we draw? What is the P-value for the problem above?
A sample of men and women who had passed their driver's test either the first time or the second time were surveyed, with the following results: Results of the driving testGender First time Second timeMen 126 211Women 135 178a) Do these data suggest that there is a relationship between gender and the passing of their driver’s test from which the present sample was drawn? Let alpha=.05
The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, seven of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population. find the p value
Students at a college were surveyed about whether they are in favor of or opposed to an increase of fees in order to build a new sports complex. The results of the student responses, broken down by gender, are found in the following table. Male Female In favor 126 105 Opposed 84 115 Is the proportion of male students in favor of the fee increase significantly different from the proportion of female students in favor of the fee? Carry out a significance test of this problem at alpha = .05. Provide each of the following in your answer. a) State the null and alternative hypotheses for this problem situation. Use correct notation. b) Compute the test statistic c) List the critical value(s) and make a decision by comparing the test statistic to the critical value(s). d) List the p-value and make a decision by comparing the p-value to alpha. e) In 1-2 complete sentences,…
A high school is proud of its advanced chemistry class, in which its 16 students scored an average of 89.3 on the statewide exam, with s = 9. a. Test the null hypothesis that the advanced class is just a random selection from the state population (μ = 84.7), using alpha = .05 (two-tailed). b. Test the same hypothesis at the .01 level (two-tailed).

A sample of 100 randomly selected children under the age of 12 showed that the average amount of time a child spends watching TV every day is 2.7 hours. The value of test statistic ( along with decision) to test the claim that the average time a child spends watching is greater than 2.6 hours ( assume alpha = 0.6 and alpha 0.01), is:
1. In the book Design and Analysis of Experiments, 8th edition (2012, John Wiley & Sons), the results of an experiment involving a storage battery used in the launching mechanism of a shoulder-fired ground-to-air missile were presented. Three material types can be used to make the battery plates. The objective is to design a battery that is relatively unaffected by the ambient temperature. The output response from the battery is effective life in hours. Three temperature levels are selected, and a factorial experiment with four replicates is run. The data are as follows: Table 11.(a) Test the appropriate hypotheses and draw conclusions using the analysis ether either firing temperature or furnace position affects the baked density of a carbon anode. The data are as follows: Table 12.(a) State the hypotheses of interest. (b) Test the hypotheses in part (a) using the analysis of variance with a = 0.05. What are your conclusions? (c) Analyze the residuals from this experiment. (d)…
