Question 1:
(a)
6.39 | confidence interval 90.% lower |
7.37 | confidence interval 90.% upper |
0.49 | margin of error |
(b) 62
(c)
1,916.51 | confidence interval 90.% lower |
2,211.49 | confidence interval 90.% upper |
147.49 | margin of error |
Question 2:
(a)
10.17 | mean Data |
0.95 | std. dev. |
(b)
8.73 | confidence interval 99.9% lower |
11.61 | confidence interval 99.9% upper |
(c) No. This confidence interval suggests that the patient no longer has a calcium deficiency.
Please give me a thumbs-up if this helps you out. Thank you!
