In a recent study conducted by Pulse Measurement Asia, their results show that a higher percentage offemales have normal resting pulse rate compared with males. Dr. Castillejo is interested to know whether thisresult also applies among gym members. Use the R commander output below to test Dr. Castillejo's claim.Write a brief report about the analysis by identifying the set of hypotheses to be tested, the appropriate test touse, and implications and recommendations of/from the conclusions.

It is being desired to estimate the average daily emission, in tons, of sulfur oxides by a large industrial plant. If n=40, x-=10,6 tons and s=5.51 tons. Construct a 95 percent large-sample confidence interval for the plant’s true average daily emission of sulfur oxides.
The waterworks commission needs to know the mean household usage of water by the residents of a small town in gallons per day. They would like to estimate to have a maximum error of 0.13 gallons. A previous study found that for an average family the variance is 2.56 gallons and the mean is 16.3 gallons per day. If they are using 80% level of confidence, how large of a same is required to estimate the mean usage of water? round answer up to the next integer.
Students on an internship program in the US Fish and Wildlife Service wishes to test the nitrogen content on rivers and waterways in the US Midwest states. 36 sample measurements were taken in various rivers and waterways and the average nitrogen content is found to be in 2.6 grams per milliliter. Find the 95% and 99% confidence intervals for the mean mercury content. Population standard deviation is 0.3 gram per milliliter. If the students want the error to be less than 0.05, how large a sample size woould be required at 95% confidence? Would the required sample size increase if a higher degree of confidence is set? O a. 95% CI: 2.50 < µ< 2.70; 99% CI: 2.47 <µ<2.73. Sample size should be 138. Sample size required will increase if the students set the % confidence higher O b.95% CI: 2.50 < µ<2.70; 99% CI: 2.47 < µ< 2.73. Sample size should be 139. Sample size required will increase if the students set the % confidence higher O c. 95% CI: 2.47 < µ<2.73; 99% CI: 2.50 < µ<2.70. Sample…

True or False? A researcher wants to be sure the mean difference in the change in blood pressure has a margin of error no more than 5 points and the difference in the standard deviation between the mean blood pressure points from the first medication used to treat high blood pressure and the second medication used to treat high blood pressure is 14 points. The desired sample size required to ensure a 95% confidence interval for the proposed study used to compare the efficacy of two medications used to treat high blood pressure during a cross-over trial is n = 31.
