Question

a survey was given to a pre - statistics class, asking, \if you could have one superpower, what would it be?\ use the results below to complete parts (a) through (e). telekinesis fly other mind read other teleport invisible telekinesis other teleport fly invisible invisible telekinesis fly teleport telekinesis fly invisible teleport fly fly invisible teleport. click here to view relative frequency bar graph b. click here to view relative frequency bar graph a. click here to view relative frequency bar graph d. click here to view relative frequency bar graph c. c. what proportion of the students chose teleporting? 0.208 (round to three decimal place as needed.) d. what proportion of the students did not choose telekinesis? 0.833 (round to three decimal place as needed.) e. what proportion of the students chose other or mind reading? (round to three decimal place as needed.)

Explanation:

Step1: Count total number of students

First, count all the responses. There are 24 responses in total.

Step2: Count number of students who chose teleporting

Count the number of times "Teleport" appears. It appears 5 times.

Step3: Calculate proportion of students who chose teleporting

The proportion is $\frac{5}{24}\approx 0.208$.

Step4: Count number of students who chose telekinesis

Count the number of times "Telekinesis" appears. It appears 4 times.

Step5: Calculate proportion of students who did not choose telekinesis

The proportion of students who did not choose telekinesis is $1 - \frac{4}{24}=\frac{20}{24}\approx 0.833$.

Step6: Count number of students who chose other or mind - reading

Count the number of times "Other" and "Mind read" appear. "Other" appears 5 times and "Mind read" appears 1 time. So in total, $5 + 1=6$ times.

Step7: Calculate proportion of students who chose other or mind - reading

The proportion is $\frac{6}{24}= 0.250$.

Answer:

0.250
