A. I buy 16 tropical fish of the species “cichlisoma negrofasciata.” I cannot determine the gender of the fish, but I’m told there is a 53% probability of a single fish being a female. Construct the appropriate probability distribution, with outcomes of 0 females to 16 females.
B. What is the probability of there being six or fewer females?
C. What is the probability of there being more than nine females?
D. What is the expected number of females?
E. What is the standard deviation of the number of females?

please answer all questions
Environmental scientists believe that there is a decline in the population of frogs around the world. They speculate that declining frog populations are a symptom of deteriorating environmental conditions. How would these scientists gather accurate data about existing frog populations? How would they use these data to speculate on previous or future population levels? Imagine that a wetland you are studying has a population of 5000 frogs, including bullfrogs, spring peepers, and mink frogs. The populations...

8. In Chapter 16, the Mantel-Haenszel method was used to investigate the association between smoking and the development of aortic stenosis for males and females. The data are contained in the data set stenosis [6] (Appendix B, Table B.20) Smoking status is saved under the variable name smoke, the presence of aortic stenosis under the name disease, and gender under the name sex. (a) Using the presence of aortic stenosis as the response, fit a logistic regression model with smoking...

I need help with the following problems:
According to a 2009 Reader's Digest article, people throw away approximately 16% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 85 grocery shoppers to investigate their behavior. What is the probability that the sample proportion is between 0.07 and 0.15? Note: You should carefully round any intermediate values you calculate to 4 decimal places to match wamap's approach and calculations. Answer...

Bags of plain M&Ms contain 24% blue candies. You have four bags of candy and select one candy from each bag. The random variable x represents the number of blue candies selected. The selected candy can be classified as either being blue (B) or not being blue (N). Answer the following questions based on this data. As always, you must show all work and formulas used in order to receive full credit. Round all decimals to three places 1. Draw...
