Reference no: EM131396761

In given Problem, test to determine (a) whether or not oral and rectal temperatures are the same; (b) whether mean oral temperature is 37°C. Use α = .05 in both (a) and (b).

Problem
A general physician recorded the oral and rectal temperatures of nine consecutive patients who made first visits to his office. The temperatures are given in degrees Celsius (°C). The following measurements were recorded:

Patient Number	Oral Temperature (deg °C)	Rectal Temperature (deg °C)
1	37.0	37.3
2	37.4	37.8
3	38.0	39.3
4	37.3	38.2
5	38.1	38.4
6	37.1	37.3
7	37.6	37.8
8	37.9	37.9
9	38.0	38.3

(a) From this data, what is your best point estimate of mean difference between oral and rectal temperatures?

(b) Give a 95% confidence interval for this difference, and state what the interval means.

(d) Give a 95% confidence interval for mean rectal temperature.
