Copy and paste an image of your table with data for Patients 1 and 2 in the space provided below. This image should include the calculated values for Mean and Std Dev. Compare the values for Mean and Std Dev for the two patients. Did both patients meet the requirements for an average of 1800.0 Calories per day? Explain in your own words your interpretation of the Std Dev values for the two sets of patient data.
Roller coaster ride: A roller coaster is being designed that will accommodate 60 riders. The maximum weight the coaster can hold safely is 12,000 pounds. According to the National Health Statistics Reports, the weights of adult U.S. men have mean 199 pounds and standard deviation 73 pounds, and the weights of adult U.S. women have mean 169 pounds and standard deviation 82 pounds.

The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 50 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n=50 ; ¯x=40.49 pounds; s=3.49 pounds a) Identify the null and alternative hypotheses? H0: H1: b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed c) Identify the appropriate significance…
There are two national college-entrance examinations, the scholastic aptitude test (SAT) and the American College Testing program (ACT). Scores on the SATs are approximately normal with mean 500 and standard deviation 100. Scores on the ACTs are approximately normal with mean 18 and standard deviation 6. Use the links provided for the Normal (Links to an external site.)calculator and the Inverse Normal (Links to an external site.) calculator to help complete the problems, you do not need to do any work out by hand. (instructions on how to use these calculators can be found in the week 5 star on the home page) a) What percent of all SAT scores are above 600? b) Which is the greater accomplishment, scoring 630 on the SAT or 22 on the ACT ? Explain your reasoning for your choice. c) How high a score in the SAT is needed to place in the top 2.5%.
In a data set with 25 scores, if the value 16 occurs 12 times, what is its relative frequency?
Irondale County has two school districts, Anaconda and Copper Canyon. In the Anaconda School District, the average score of fifth graders on the Iowa Test of Basic Skills (ITBS) was 50. In the Copper Canyon School District, the average ITBS score for 5th graders was 72. Can we conclude that the average score for all fifth graders in Irondale County who took the test is 61, the mean of 50 and 72? If so, explain why. If not, tell what additional information would be needed in order calculate the mean ITBS score for all their fifth graders.
