Question
In a random sample of males, it was found that 21 write with their left hands and 224 do not. In a random sample of females, it was found that 67 write with the
left hands and 448 do not. Use a 0.01 significance level to test the claim that the rate of left-handedness among males is less than that among females.
Complete parts (a) through (c) below.
OF. Ho Pt P2
H P1 <P2
O E. Ho P1SP2
D. Ho P1 P2
H Pi #P2
Identify the test statistic.
(Round to two decimal places as needed.)
Identify the P-value.
P-value =
(Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
v the null hypothesis. There
V evidence to support the claim
The P-value is
V the significance level of a = 0.01, so
that the rate of left-handedness among males is less than that among females.
b. Test the claim by constructing an appropriate confidence interval.
The 98% confidence interval is < (p,-P2) <U
(Round to three decimal places as needed.)
What is the conclusion based on the confidence interval?
V There
Vevidence
0, it appears that the two rates of left-handedness are
Because the confidence interval limits
to support the claim that the rate of left-handedness among males is less than that among females.
c. Based on the results, is the rate of left-handedness among males less than the rate of left-handedness among females?
O A. The rate of left-handedness among males does not appear to be less than the rate of left-handedness among females.
O B. The rate of left-handedness among males does appear to be less than the rate of left-handedness among females because the resuits are not
statistically significant
O C. The rate of left-handedness among males does appear to be less than the rate of left-handedness among females because the results are
statistically significant.
O D. The results are inconclusive.
