A survey of 241 randomly selected students at Bellevue University showed that only 23% checked their campus email account on a regular basis. Construct and interpret a 99% confidence interval for the percentage of students at the university that check their email on a regular basis. Correctly round your results to the nearest tenth of a percent in your conclusion sentence.
Added by Ray C.
Step 1
To calculate the sample proportion, we use the given percentage of students who check their email regularly, which is 23% of 241 students. The sample proportion \( p \) is: \[ p = \frac{23}{100} \times 241 = 0.23 \times 241 = 55.43 \approx 55 \] Show more…

A survey of 279 randomly selected students at Bellevue University showed that only 87 checked their campus email account on a regular basis. Construct and interpret a 90% confidence interval for the percentage of students at the university that check their email on a regular basis. Please state the number favorable (x), sample size (n), p-hat, critical value, margin of error, confidence interval, and upper and lower limit. Also show the formulas in excel, if possible. Correctly round your results to the nearest tenth of a percent in your conclusion sentence.

A survey of 137 randomly selected students at one college showed that only 86 checked their campus email account on a regular basis. Construct a 98% confidence interval for the percentage of students at the college who do not check their email account on a regular basis. Round to one decimal place.
