Thus, the experiment had 11 "successes" and 13 "failures." Use all the information provided in the steps above to determine whether the conditions for creating a confidence interval are satisfied. Part 10 b) Construct a 9595% confidence interval for the proportion of "red snapper" packages that were a different kind of fish. The confidence interval for a population proportion, p, is given by the following expression, where ModifyingAbove p with caretp is the sample proportion, zstar* is the critical value corresponding to the confidence level, and SE left parenthesis ModifyingAbove p with caret right parenthesisSEp is the standard error of the sample proportion. ModifyingAbove p with caret plus or minus z Superscript star Baseline times SE font size decreased by 5 left parenthesis ModifyingAbove p with caret right parenthesispz*SE p Part 11 The standard error of the sample proportion, SE left parenthesis ModifyingAbove p with caret right parenthesisSEp, is an estimate of the standard deviation of the population proportion, and is given by the following formula, where ModifyingAbove q with caret equals 1 minus ModifyingAbove p with caretq=1p and n is the sample size. SE font size decreased by 5 left parenthesis ModifyingAbove p with caret right parenthesis equals StartRoot StartFraction ModifyingAbove p with caret ModifyingAbove q with caret Over n EndFraction EndRootSE p= pq n Part 12 Use technology to construct the 95% confidence interval
