Evaluate.A simple random sample of 262 leukemia cases consisted of 150 males and 112 females. Does this provide the evidence of a gender difference for the disease? Observed proportion, male = 150/ (150+112) = 0.5725. Test Ho = p = 0.5.

Failure to grow normally during the first year of life (perinatal growth failure) was observed in 33 of 249 very-low birthweight babies. The 90% confidence interval was 0.1383 +/- 0.0357. Write a statement interpreting the 90% confidence interval. (2 points) A simple random sample of 262 leukemia cases consisted of 150 males and 112 females. […]

Evaluate A= mean+ -kxStandard deviation and B= mean -kxStandard deviation. Use the function COUNTIFS to count the number of data points that are between A and B and see whetherbthis agrees with Chebyshev’s theory). For part b) see whether your results agree with the empirical rule – 68-95-99.7% rule for k=1,2,and 3( This is not in our text but I discussed it in one of our meetings.

The following is your project (worth 10% of grade): Generate 200 random integers between 1 and 9999 a) verify Chebyshev’s Theorem (pages 135 –137 text for k=1.5,2,3 b) determine whether these data is normal or approxinmately normally distributed Justify your decision. This project should be no more than 2-4 pages ( if you use Excel […]

Compare between our draft with the (Sample Grade A – previous project)

1-you’ll find the final draft of our project named as (Project-Du) – ” Which I need you to edit on it and highlight what did do you edit with gray color so I can check”. So, you need to compare the final project with the Guidlines PDF and check that we followed our instructor directions. […]

Six people from different occupations were interviewed for a survey, and their annual salaries were as follows: $12,000, $20,000, $25,000, $37,000, $67,000, and $125,000. What is the mean annual salary for the six people?

Determine how many units on Desmos represent a unit of time (x-axis) and a unit of interest (y-axis). This will be necessary for interpreting your model in a real-world context.

PART A – MODELING YOUR TREND WITH FUNCTIONS An example can be found at this link Using your Desmos workbook, begin plotting base functions and transforming them to attempt to model your trend. Do this by starting with an appropriate base function (ie. y = 2x) and applying your understanding of transformations. See the link […]
