Number of giraffes
Sample mean
deviation
Take Sample
Enter the values of the sample size, the point estimate of the mean, the sample standard deviation, and the critical value you need for your 95%
confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute".
Sample size:
Point estimate:
Standard error:
5
Sample standard deviation:
Critical values
Margin of error:
0.005 = 2.947
Critical value:
10.010 = 2.602
95% confidence interval:
10.025 = 2.131
Compute
0.050 1.753
0.100=1.341
(b)
Based on your sample, graph the 95% confidence interval for the population mean of all the heights of fully grown male West African giraffes.
• Enter the values for the lower and upper limits on the graph to show your confidence interval.
