A random sample of 6 steam boiler pressure has a mean of 760 psi (pound per square inch) with its population standard deviation is 28 psi. Use this information and thelevel of significance a=0.05 to test whether the true average steam boiler pressure from which this sample came is 790 psi.i) State the null and alternative hypotheses.Ho: m ♦H₁: m+ii) Calculate the test statistic and find the critical value.Answer:x = (a)σ= (b)Zo= (c)Zcritical value = (d)(a)(b)(c)(2 d.p)(d)iii) State the decision and conclusion.Decision:+Ho.Conclusion: There is+ evidence to believe that the true average steam boiler pressure from which this sample came is 790 psi.

From the provided information, Sample size (n) = 6 Level of significance (α) = 0.05

The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.025 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions? A. Determine the test statistic. F= (Round to two decimal places as needed.) B. Identify the P-value. P-value= (Round to two decimal places as needed.)
A random sample is obtained from a normal population with a mean of u=95 and a standard deviation of o=40. The sample mean is M=86. a.is the a representative sample mean or an extreme value for a sample of n=16 scores?
As a bonus assignment a former student checked if your professor gave a statisticallysignificant difference in grades between his male and female students. She based herstudy based on grades assigned in intermediate Econ courses (Econ 303, 305 and 317)and her sample included nm = 485 male students and nf = 264 female students. Theaverage grades received were xm = 84.6 and xf = 85.8 The population standad deviation were σ m = 12.0 and σ f = 11.4 8. From the same extra-credit study as in question 7 see above, this former student found that the proportion of female students in principle courses (Econ 203, 205) was ?̅? = 0.380, while the proportion of female students in intermediate courses (Econ 303, 305, 317) was ?̅? = 0.352. The principle courses sample size was np = 782, while the intermediate courses sample size was ni = 749. Test the hypothesis that female students are less in intermediate courses using a 90% confidence level and the p-value approach.
