Question
There is a popular lottery and what she take it is called a scratcher. And advertisement for those lottery claims that 34% of the population of all the scratchers or wedding ones. Do you want to research this claim by selecting a random sample of 75 scratchers. Follow the steps below to construct a 99% confidence interval for the population proportion of all winning scratchers. The state whether the confidence interval you construct contradicts the advertisements Claim 
Constructing a confidence interval to test a claim about a.
(a)
Click on "Take Sample" to see the results from the random sample.
Number
Proportion
Take Sample
Winning scratcher
18
0,24
Losing scratcher
57
0.76
Enter the values of the sample size, the point estimate of the population proportion, and the critical value you need for your 99% confidence interval.
(Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute".
Sample size:
Standard error:
Critical values
Point estimate:
20.005 -2.576
Margin of error:
Z0.010 =2.326
Critical value:
20.025 =1.960
99% confidence interval:
Z0.050-1.645
Compute
20.100 =1.282
(b)
Based on your sample, graph the 99% confidence interval for the population proportion of all winning scratchers.
• Enter the values for the lower and upper limits on the graph to show your confidence interval.
• For the point (), enter the claim 0.34 from the advertisement.

(b)
Based on your sample, graph the 99% confidence interval for the population proportion of all winning scratdchers.
Enter the values for the lower and upper limits on the graph to show your confidence interval.
• For the point (), enter the claim 0.34 from the advertisement.
99% confidence interval:
0.000

0.000
1.000
(c) Does the 99% confidence interval you constructed contradict the claim from the advertisement?
Choose the best answer from the choices below.
O No, the confidence interval does not contradict the claim. The proportion 0.34 from the advertisement is inside the 99%
confidence interval.
O No, the confidence interval does not contradict the claim. The proportion 0.34 from the advertisement is outside the
99% confidence interval.
O Yes, the confidence interval contradicts the claim. The proportion 0.34 from the advertisement
s inside the 99%
confidence interval.
O Yes, the confidence interval contradicts the claim. The proportion 0.34 from the advertisement
confidence interval.
