19.17,. The subject under investigation is the measureof dependence of Tamil or. words of Sanskrit origin. One newspaperarticie reporting the proceedings of Constituent Assembly contained2025 words of which 729 words were declared by a literary critic tobe of Sanskrit origin. A second article by the same author describingatomic research contained 1600 words of which 640 words were dec-lared by the same critic to be of Sanskrit origin. Assuming thatsimple sampling conditions held, estimate the limits for the propor-tion of Sanskrit terms in the writer's vocabulary, and examinewhether there is any significant difference in the independence ofthis writer in words of Sanskrit origin in writing on these twosubjects.

According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.33.Suppose a random sample of 109 traffic fatalities in a certain region results in 47that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the α=0.05 level of significance?
An agronomist randomly selected 20 matured calamansi trees of one variety and have a mean height of 10.8ft with standard dev of 1.25ft, while another 12 randomly selected calamansi trees of another variety have a mean height of 9.6ft with standard dev of 1.45ft. Test whether the difference of 2 sample means is significant at α = 5%.
1) A cement producer, manufactures and then fills 40kg-bags of powder cement on twodistinct production tracks located in separate suburbs. To determine whether differencesexist between the average fill rates for the two tracks, a random sample of 25 bags fromTrack 1 and a random sample of 16 bags from Track 2 were recently selected. Each bag’sweight was measured and the following information measures from the samples arereported:Production ProductionTrack 1 Track 2n1 = 25 n2 = 16x2 = 40.02 x1 = 39.87 s1 = 0.59 s2 = 0.88 Supervision believes that the fill rates of the two tracks are normally distributed with equalvariances.Construct a 95% confidence interval estimate of the true mean difference between the twotracks.--------------------------------------------------------------------------------------------------------------2) Two independent simple random samples were selected from two normallydistributed populations with unequal variances yielded the following information:Sample 1…
A simple random sample of heights of 6400 Englishmen has a mean of67.85 inches and SD 2.56 inches, while a simple random sample of heightsof 1600 Australians has a mean of 68.55 inches and SD of 2.52 inches. Dothe data indicate that Australians are, on the average, taller thanEnglishmen?
A suburban hotel derives its revenue from its hotel and restaurant operations.

The following table shows the results of two random samples that measured the average number of minutesper charge for AA Lithium-ion (Li-ion) rechargeable batteries versus Nickel-Metal Hydride (NiMH)rechargeable batteries. Perform a hypothesis test using α =0.05 to determine if the average number ofminutes per charge for Li-ion batteries last longer than NiMH batteries. Assume the population variances forthe number of minutes per charge are unequal.Li-ion NiMH110 8798. 9290 9087. 8992 89101 8898 8788 9187 9299 86100. 88103 9089 92105 90909781 1)State the hypotheses. 2) Compute the test statistic and Compute the p-value. 3) Make the decision and Summarize the results.
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?
