Question

Qs 2: A sample of 25 freshman nursing students made a mean score of 77 on a test designed to measure attitude toward the dying patient. The sample standard deviation was 10. Do these data provide sufficient evidence to indicate, at the .05 level of significance, that the population mean is less than 80? What assumptions are necessary?

Step 1

• Sample size (n) = 25. • Sample mean (x̄) = 77. • Sample standard deviation (s) = 10. • The claim is that the population mean (μ) is less than 80. • Significance level (α) = 0.05. Show more…
