Data were collected from a survey given to graduating college seniors on the number of times they had changed majors. From that data, a probability distribution was constructed. The random variable X is defined as the number of times a graduating senior changed majors. It is shown below: xx 0 1 2 3 4 5 6 7 8 P(X=x)P(X=x) 0.184 0.307 0.228 0.158 0.067 0.037 0.016 0.002 0.001 Given that a randomly selected person did change majors, what is the probability that he or she changed majors more than three times?
The total energy need during pregnancy is normally distributed, with mean of 2600 kcal/day and a standard deviation of 50 kcal/day. What is the probability that a random sample of 20 pregnant women has a mean energy need of more than 2625 kcal/day? Is this result unusual? [Recall unusual means the probability is less than 5%]

Let random variable QQ represent the number of employees who work at a certain restaurant on a given day. The following table shows the probability distribution of the random variable QQ. Which of the following claims is best supported by the table? The most likely number of employees who work on a given day is 24. A The mean number of employees who work on a given day is equal to the median number of employees who work on a given day. B The mean number of employees who work on a given day is greater than the median number of employees who work on a given day. C The mean number of employees who work on a given day is less than the median number of employees who work on a given day. D On a given day, the number of employees who work at the restaurant occurs with equal probabilities.

Oxygen demand is a term biologists use to describe the oxygen needed by fish and other aquatic organisms for survival. The Environmental Protection Agency conducted a study of a wetland area. In this wetland environment, the mean oxygen demand was μ = 9.1 mg/L with 95% of the data ranging from 6.7 mg/L to 11.5 mg/L. Let x be a random variable that represents oxygen demand in this wetland environment. Assume x has a probability distribution that is approximately normal. QUESTION: (b) An oxygen demand below 8 indicates that some organisms in the wetland environment may be dying. What is the probability that the oxygen demand will fall below 8 mg/L? (Round your answer to four decimal places.)

Oxygen demand is a term biologists use to describe the oxygen needed by fish and other aquatic organisms for survival. The Environmental Protection Agency conducted a study of a wetland area. In this wetland environment, the mean oxygen demand was μ = 9.9 mg/L with 95% of the data ranging from 7.3 mg/L to 12.5 mg/L. Let x be a random variable that represents oxygen demand in this wetland environment. Assume x has a probability distribution that is approximately normal. (a) Use the 95% data range to estimate the standard deviation for oxygen demand.
