Find out the correlation coefficient.
Bicycle helmet use. Table lists data from a cross-sectional survey of bicycle safety. The explanatory variable is a measure of neighbourhood socioeconomic status (variable_RFM). The response variable is "percent of bicycle riders wearing a helmet" (P_Helm).
Percent of school children receiving free or reduced-fee lunches at school (variable P_RFM) and percent of bicycle riders wearing a helmet (variable P_HELM). Data for the study was recorded by field observers in October of 1994.

Determining probability values using the Binomial distribution.Use the Binomial distribution to determine the probability that four or more of the contracts are in breach of the tendering guidelines.
Suppose you bid $12000. What is the probability that your bid will be accepted?
If a blue ball is selected you win nothing. Let X be the amount that you win. The expected value of X and let the random variable X be a random number with the uniform density curve given below
Two groups of students are asked to rank their preference for six types of soft drinks. The following table shows their rankings.
If x is a binomial random variable where n = 100 and p = .1, find the possibility that x is less than or equal to 10 using the normal approximation to the binomial.
Decision making under risk is the same as decision making under uncertainty because in both the probabilities are unknown.
Given same values n=20, p=0.6, and x=17, calculate probability of x successes in n independent trails of experiment.

The diameters of oranges in a certain orchard are normally distributed with a mean of 5.26 inches and a standard deviation of 0.500 inches.
How large a sample is required if the 97 percent level of confidence is used and the estimate is to be within $2,500? The standard deviation is $16,000.
At the end of 24 weeks of treatment, subjects were classified as responders or non-responders to treatment based on a battery of psychological tests.
A researcher was interested in determining whether incentives affect the response rate in surveys. A simple random sample of 50 adult residents of a large city was selected. All were mailed a survey and promised a check upon returning a completed ..
