Question

In a study of red/green color blindness, 900 men and 2450 women
are randomly selected and tested. Among the men, 80 have red/green
color blindness. Among the women, 7 have red/green color blindness.
Test the claim that men have a higher rate of red/green color
blindness.

(e) Construct the 90% confidence interval for the difference between the color blindness rates of men and women.

________ < (Pm-Pw) <______

Answer #1

The statistical software output for this problem is:

From above output, 90% confidence interval will be:

**0.0703 < (pm - pw) < 0.1017**

(a) State the null hypothesis:...

Color Blindness The most common form of color blindness is
red–green color blindness. People with this type of color blindness
cannot distinguish between green and red. Approximately 8% of all
males have red–green color blindness, while only about 0.64% of
women have red–green color blindness. In 2000, 49.1% of all
Americans were male and 50.9% were female according to the U.S.
Census Bureau

is color blind?
b) What is...

In humans, red-green color -blindness is a recessive X-linked
trait. A man with red-green colorblindnes marries a normal-vision
women whose father was color-blind. As the genitic counselor,
construct a Punnett square to determine the genotypic and
phenotypic possibilities of their children.

Independent simple random samples of 950 men and 2500 women are
tested. Among the men in the sample, 81 have red/green color
blindness. Among the women in the sample, 9 have red/green color
blindness.
The value of the test statistic is z= (round
to at least three decimal places).

In a survey, 500 men and 500 women were randomly selected. Among
the men, 52 had been ticketed for speeding within the last year,
whereas 27 of the women had been ticketed for speeding during the
same period (based on data from R. H. Bruskin Associates).
(a) At the 0.01 significance level, test the claim that women
have lower rate of speeding tickets.
Original claim is made by the Answer hypothesis.
Original claim is: pwomen - pmenAnswer

For the color blindness data in Exercise 16.HE.A, we
wish to test a hypothesis to answer the question, “Has the instance
of color blindness increased from the historical rate of
1%?”
"16.HE.A: It is estimated that 1%
of the population suffers from red/green color blindness (Source:
USA Today). The ophthalmology department of a large university
medical center randomly tests 300 men. 11 are found to have this
type of color blindness.
