A simple random sample of 42 men results in a standard deviation of 10.09 beats per minute. Use the sample results to test the claim that men have pulse rates that have a standard deviation equal to the population standard deviation of 10.98 beats per minute at the 10% significance level. Assume that the sample is from a normally distributed population. What are the correct hypotheses? (Select the correct symbols and values.) H0: Select an answer μ p̂ σ s x̄ s² σ² p ? ≤ ≥ > = ≠ < beats per minute Original claim = Select an answer H₁ H₀ H1: Select an answer μ s x̄ p̂ σ σ² s² p ? ≥ < = ≤ > ≠ beats per minute Enter the critical values, along with the significance level and degrees of freedom χ2χ2(αα,df) below the graph. (Graph is for illustration only. No need to shade.) X2Χ2(,) = < X2Χ2(,) = (Round to three decimal places.) Test Statistic = (Round to three decimal places.) Decision: Select an answer Reject the null hypothesis Accept the null hypothesis Fail to reject the null hypothesis Accept the alternative hypothesis . Conclusion: Select an answer The sample data supports There is not enough evidence to support There is sufficient evidence to warrant rejection of There is not sufficient evidence to warrant rejection of the claim that men have pulse rates that have a standard deviation equal to the population standard deviation of 10.98 beats per minute.
