...Statistics Presented by: On 26th may, Solution to Question One n=100 mean=30 sd=8 CI=95% Zα/2=1.96
I. Between 28.4 and 31.6
standard error= 8/10=0.8 ᵶ1=(28.4-30)/0.8= -2 Therefore area = -0.4772
ᵶ2= (31.6-30)/0.8= 2 Therefore area = 0.4772
P( 28.4≤µ≤31.6)= P( 31.6) – P( 28.4)
= 0.4772- ( -0.4772)= 0.9544
0.9544*100=95.44%, thus it is 95% sure that the population mean lies between 28.4 and 31.6
II. Between 27.0 and 33.0
ᵶ1=(27.0-30)/0.8= -3.75 therefore area = -0.4999 ᵶ2 = (33.0-30)/0.8 = 0.375 therefore area = 0.4999
P(27.0 and 33.0)= 0.4999-(-0.4999)=0.9998
