You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 0.22. You use a significance level of a = 0.005. Ho:p = 0.22 H1:p < 0.22 You obtain a sample of size n = 716 in which there are 149 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) a O greater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null As such, the final conclusion is that...

Question
Transcribed Image Text:You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than
0.22. You use a significance level of a = 0.005.
Ho:p = 0.22
H1:p < 0.22
You obtain a sample of size n = 716 in which there are 149 successes.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =
The p-value is...
O less than (or equal to) a
O greater than a
This test statistic leads to a decision to...
O reject the null
O accept the null
O fail to reject the null
As such, the final conclusion is that...
O There is sufficient evidence to warrant rejection of the claim that the accuracy rate for fingerprint
identification is less than 0.22.
O There is not sufficient evidence to warrant rejection of the claim that the accuracy rate for
fingerprint identification is less than 0.22.
O The sample data support the claim that the accuracy rate for fingerprint identification is less than
0.22.
O There is not sufficient sample evidence to support the claim that the accuracy rate for fingerprint
identification is less than 0.22.
