Complete Question:
Chapter 6, Section 1-D, Exercise 009 Is a Normal Distribution Appropriate? In each case below, is the sample size large enough so that the sample proportions follow a normal distribution?
a) n=600 p=0.2
b) n=20, p=0.4
if np=10 and npq=10 then the data follows normal distribution
a) np= 120,
q= 1-0.2= 0.8
npq= 600 ×0.2×0.4 = 48
Normal distribution is appropriate and sample size is large enough
b) np= 8
q= 1-0.4= 0.6
npq= 20 × 0.4×0.6= 4.8
sample size is not large enough so normal distribution is not appropriate.
Answer:
[least] 6 3/8, 6 5/6,6 1/2, 6 3/4 [greatest]
Step-by-step explanation:
Common denominator- 48
27/4= 324/48
13/2=312/48
41/6=328/48
51/8=306/48
[least] 6 3/8, 6 5/6,6 1/2, 6 3/4 [greatest]
Hope this helps :D
Answer:C and E
Step-by-step explanation:
Answer: A. S(n) =11+4n
Step-by-step explanation:first row is 15 so 11+(1×4) and 11+(4×2)=19 and so onn.
