Computer software generated 500 random numbers that should look like they are from the uniform distribution on the interval 0 to 1. They are categorized into five groups: (1) less than or equal to 0.2 (2) greater than 0.2 and less than or equal to 0.4, (3) greater than 0.4 and less than or equal to 0.6, (4) greater than 0.6 and less than or equal to 0.8, and (5) greater than 0.8. The counts in the five groups are 113, 95, 108, 99, and 85, respectively.
1. The probabilities for these five intervals are all the same. What is this probability?2. Compute the expected count for each interval for a sample of 500.3. Perform the goodness of fit test and summarize your results.
Discuss whether this variable should be placed in the model as an ordinary quantitative variable or by means of four 0, 1 indicator variables.
Multiple choice questions based on regression - A regression and correlation analysis resulted in the following information
Mean income of $30,000and a standard deviation of $3,000. What is the income that separates the top 25% from the lower 75% of the incomes?
That's a much larger sample than standard sample surveys. In spite of this, we can't trust the result to give good information about any clearly defined population. Why?
If 55 people are chosen at random, what is the probability that the sample mean of IQ scores will not differ from the population mean by more than 2 points?
