Developing an Understanding of Statistical Concepts
In Exercises 11.7-11.12, calculate the value of the test statistic, set up the rejection region, determine the p-value, interpret the result, and draw the sampling distribution.
11.7 H : H = 1000 H1: μ#1000
σ = 200, n = 100, x = 980, a = .01
11.8 Ho:
50
H1: μ> 50
σ = 5, n = 9, x = 51, α = .03
11.9 Ho: μ 15 H1:
70
σ = 20, n = 100, x = 80, a = .01
11.12 Ho: μ= 50
H1: μ< 50
σ = 15, n = 100, 48, a = .05
For Exercises 11.13-11.19, calculate the p-value of the test to determine that there is sufficient evidence to infer each research objective.
11.13 Research objective: The population mean is less
than 250.
σ = 40, n = 70, x = 240
11.14 Research objective: The population mean is not equal to 1,500.
σ = 220, n = 125, x = 1525
11.15 Research objective: The population mean is greater
than 7.5.
σ = 1.5, n = 30, x = 8.5
11.16 Research objective: The population mean is greater than 0.
σ = 10, n = 100, x = 1.5
11.17 Research objective: The population mean is less than 0.
σ = 25, n = 400, x = -2.3
