Chapter 10.4, Problem 44E
Paint used to paint lines on roads must reflect enough light to be clearly visible at night. Let μ denote the mean reflectometer reading for a new type of paint. A test of H0: μ = 20 versus Ha: μ > 20 based on a sample of 15 observations resulted in t = 3.2. What conclusion is appropriate at each of the following significance levels?
- a. α = 0.05
- b. α = 0.01
- c. α = 0.001

The mean arterial pressure (or MAP, average arterial pressure in one cardiac cycle) is
a measure for perfusion status. You are interested to know if it is possible to predict
an adult's MAP (Y) based on the body surface area (X). Suppose you randomly
selected 50 adults, and measured their mean arterial blood pressure (in mmHg) &
body surface area (in m2). The results are reflected below:
I = 1.6 s, = 0.5 y = 80.1 s, = 16.9 r 0.8

The Figure below shows the calibration curve for the determination of an analyte. Knowing that the replicas of a sample showed the following signs: 0.114; 0.117 and 0.115, answer: Which option below shows the mean concentration (mg/L), standard deviation (mg/L) and relative standard deviation (%), respectively?
a) 144.5 mg/L; 6.7 mg/L and 1%b) 244.5 mg/L; 3.3 mg/Le 10%c) 227.9 mg/L; 3.1 mg/l and 1%
In the graph, the y axis represents the signal and the x axis the concentration mg/L
