Question

A poll was conducted to find out whether people thought the United States should be involved in restrictions made on other countries’ nuclear programs. Respondents who answered positively were then asked to select a reason for this involvement. The respondents were grouped into two age brackets. Using a 0.01 significance level, a test statistic of 19.529 and a critical value of 9.210 were found. Use these values to test the claim that the age bracket is independent of the choice for the cause of the United States’ involvement in other countries’ nuclear programs.

	Reject the null hypothesis; there is not sufficient evidence to warrant rejection of the claim that the sex of the age bracket is independent of the choice for the cause of the United States’ involvement in other countries’ nuclear programs.
	Fail to reject the null hypothesis; there is not sufficient evidence to warrant rejection of the claim that the age bracket is independent of the choice for the cause of the United States’ involvement in other countries’ nuclear programs.

Answer 1

Given that

test statistics = 19.529

Critical value = 9.210

: Test statistic > critical value

We reject that 1% level of significance .

There is sufficient evidence to warrant rejection of the claim that the age bracket is independent of the choice of the cause of the united states involvement in other countries nuclear programs.
