Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Suppose that a statistics teacher asks his students to each randomly pick one of the numbers 0, 3, 5, 7. His general theory is that the proportion who pick the number 0 will be less than what would be expected from random selection. Use p to represent the population proportion that would pick the number 0. (a) What is the specific value of p that corresponds to true random selection? p = (b) In terms of p, write null and alternative hypotheses for this situation. Ho Ha: P <
