Question

A survey was conducted to determine, on average, how long patients have to wait to see a doctor. The number of patients that ended up waiting up to 2 hours to see a doctor, recorded in 10-minutes intervals, is given in the table below. Calculate the standard deviation for this distribution. Explain what it means in the context of this problem.

Waiting time(mins) |
10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 | 100 | 110 | 120 |

Frequency of Occ. | 1 | 4 | 15 | 20 | 35 | 42 | 28 | 19 | 13 | 5 | 2 | 1 |

6. The amount of time that you have to wait before seeing the
doctor in the doctor's office is normally distributed with a mean
of 15.2 minutes and a standard deviation of 15.2 minutes. If you
take a random sample of 35 patients, what is the probability that
the average wait time is greater than 20 minutes? (Hint: Round the
probability value to 2 decimal places.) Show your
calculations.
A. 0.16
B. 0.09
C. 0.03
D. 0.28...

The data collection is conducted by randomly selecting 51
persons whose ages are between 25-30 and interviewing the average

a survey was conducted on sky divers attitudes toward the
practise example activities. They were asked to state the extent to
which they found the example activities helpful for their learning
in sky diving on a 7 point scale (1 = strongly disagree; 4 =
neutral; 7 = strongly agree). Gender and Lecture Attendance in sky
diving were also recorded. A random sample of 60 students was
selected Rating_catwas created to re-group the
simulation ratings into three categories: Disagree (1,...

Instructions: In 1974, Loftus and Palmer conducted a classic
study demonstrating how the language used to ask a question can
influence eyewitness memory. In the study, college students watched
a film of an automobile accident and then were asked questions
about what they saw. One group was asked, “About how fast were the
cars going when they smashed into each other?” Another group was
asked the same question except the verb was changed to “hit”
instead of “smashed into.” The...

1. A city official claims that the proportion of all commuters
who are in favor of an expanded public transportation system is
50%. A newspaper conducts a survey to determine whether this
proportion is different from 50%. Out of 225 randomly chosen
commuters, the survey finds that 90 of them reply yes when asked if
they support an expanded public transportation system. Test the
official’s claim at α = 0.05.
2. A survey of 225 randomly chosen commuters are asked...
