Question 14 of 20
1.0/ 1.0 Points
Accepted characters
: numbers, decimal point markers (period or comma), sign indicators (-), spaces
(e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation).
NOTE:
For scientific
notation, a period MUST be used as the decimal point marker.
Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly stated values.
For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.
The CEO of a software company is committed to expanding the proportion of highly qualified women in
the organization’s staff of salespersons. He believes that the proportion of women in similar sales
positions across the country is less than 45%. Hoping to find support for his belief, he directs you to test
H
0
: p
.45 vs H
1
: p < .45.
In doing so, you collect a random sample of 50 salespersons employed by his company, which is thought
to be representative of sales staffs of competing organizations in the industry. The collected random
sample of size 50 showed that only 18 were women.
Compute the test value that you would use in conducting this test. Place your answer, rounded to 3
decimal places, in the blank. For example, -2.345 would be a legitimate entry.
-1.279

A survey determines that mint chocolate chip is the favorite ice cream flavor of 6% of consumers. An ice
cream shop determines that of 260 customers, 20 customers stated their preference for mint chocolate
chip.
Find the P-value that would be used to determine if the percentage of customers who prefer mint
chocolate chip ice has increased at a 5% level of significance.
P-value:
0.1351
Round your answer to four decimal places as necessary.

Suppose a firm that produces light bulbs wants to know whether it can say that its light bulbs typically last
more than 1500 hours. Hoping to find support for their claim, the firm collects a random sample of n = 25
light bulbs and records the lifetime (in hours) of each bulb. The information related to the hypothesis test
is presented below.
