1. give the mean and standard deviation of the sample distribution of hatp. give your answers in decimal form. (example: 0.398)
mean (round to two decimal places) =
standard deviation (round to three decimal places) =
determine the probability that more than 45% of those in a survey would have received a phishing email.
2. what is the z-score for a 45% probability? (round to three decimal places, example: 3.456)
z =
3. what is the probability that more than 45% of those in a survey would have received a phishing email? give your answer in decimal form, rounding to three decimal places. (example: 0.398)
