Question

Crave is a large subscription-based internet streaming service for movies and television shows. Suppose the proportion of Saskatchewanians who have a Crave subscription is 0.15. Suppose the population of Rosetown, Saskatchewan is 2700 people.

b) What is the probability that more than 18% of people in Rosetown, Saskatchewan have a Crave subscription? Use your standard deviation from part a). [3 marks]

Note: in your answer to question 3 part b), please show all of
the following:

1) The probability you are asked to calculate (no need to specify
the distribution – it’s the same as in part a))

2) Any tricks you use

3) Your rounded z-score (remember to round your z-score to 2
decimal places)

4) Your final probability

Answer #1

4. [7 marks] Crave is a large subscription-based internet
streaming service for movies
and television shows. Suppose the proportion of Saskatchewanians
who have a Crave
subscription is 0.15. Suppose the population of Rosetown,
Saskatchewan is 2700 people. What is the probability that between
14% and 17% of people in Rosetown, Saskatchewan have a Crave
subscription? Round your standard deviation to 4 decimal
places.

NetFlix offers viewers access to stream movies and television
shows through its subscription-based service. When it first offered
a standard standalone streaming package in 2011, a large share of
consumers were delighted that for $7.99 per month, they could

In 2017, the price again increased to $10.99 per month. Despite
these price increases, NetFlix remains popular....

Suppose an online television and movie streaming service has
determined that viewers who watched the entire first season of one
of its original series take an average of 5.7801 days, with a
standard deviation of 4.0205 days. One of their analysts wants to
determine at a significance level of 0.05 whether new customers who
begin watching the series within a week of the start of their
subscription finish watching the season more quickly. She selects a
simple random sample of...

Suppose that the population proportion of Internet users who say
that they use Twitter or another service to post updates about
themselves or to see updates about others is 19%. about selecting
random samples from a population in which 19% are Twitter
users.
(a) Describe the sample space for selecting a single person.
(b) If you select three people, describe the sample space.
Think
(c) Using the results of part (b), define the sample space for the

1. Suppose your customers' incomes are normally distributed with
a mean of $37,500 with a standard deviation of $7,600. What is the
probability that a randomly chosen customer earns less than
$36,000? (Round your answer to three decimal places, eg 0.192.)
2. A continuous random variable X has a normal
distribution with mean 12.25. The probability that X takes a value
less than 13.00 is 0.82. Use this information and the symmetry of
the density function to find the probability...

Pandora is the Internet’s most successful subscription radio
service. As of June 2013, it had over 200 million registered users

(15.28) Almost all medical schools in the United States require
students to take the Medical College Admission Test (MCAT). To
estimate the mean score μμ of those who took the MCAT on your
campus, you will obtain the scores of an SRS of students. The
scores follow a Normal distribution, and from published information
you know that the standard deviation is 6.2. Suppose that (unknown
to you) the mean score of those taking the MCAT on your campus is...

1. Find the area under the standard normal curve (round to four
decimal places)
a. To the left of z=1.65
b. To the right of z = 0.54
c. Between z = -2.05 and z = 1.05
2. Find the z-score that has an area of 0.23 to its right.
3. The average height of a certain group of children is 49
inches with a standard deviation of 3 inches. If the heights are
normally distributed, find the probability that a...

The Business Case for Agility
“The battle is not always to the strongest, nor the
race to the swiftest, but that’s the way to bet
’em!” —C. Morgan Cofer
In This Chapter
This chapter discusses the business case for Agility,
presenting six benefits for teams and the enterprise. It also
