Question

. A random sample contains 30 observations. Determine the p-VALUE for each value of the calculated test statistic below and state your decision about the null hypothesis in each part by comparing the p-VALUE to

� = 0.10 H0:

� = 38 Ha: � ≠ 38 SHOW WORK; each correct answer 0.5 point)

a) t = 1.311

b) t = 2.045

c) t = -1.4421

Answer 1

Ho :   µ =   38
Ha :   µ ╪   38
Level of Significance ,    α =    0.10

t = 1.311

p-Value   =   0.2001
Decision:   p-value>α, Do not reject null hypothesis   
............

t = 2.045

p-Value   =   0.0500
Decision:   p-value<α, Reject null hypothesis   
............

t = -1.4421

p-Value   =   0.1600
Decision:   p-value>α, Do not reject null hypothesis   
................
