You obtain a sample of sizen

=

658

n=658

in which there are 524 successful observations.

1. What is the test statistic for this sample?
3. test statistic =Round to 3 decimal places.
5. What is the p-value for this sample?
7. P-value =Use TechnologyRound to 4 decimal places.
9. The p-value is...

• less than (or equal to)
• greater than

3. This test statistic leads to a decision to...

• reject the null
• accept the null
• fail to reject the null

3. As such, the final conclusion is that...

• There is sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.83.
• There is not sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.83.
• The sample data support the claim that the population proportion is less than 0.83.
• There is not sufficient sample evidence to support the claim that the population proportion is less than 0.83.
