Answer: B
Step-by-step explanation:
Answer: A. $4.12
Step-by-step explanation:
Y=a(1+r/n)^nt is the equation we use to solve this.
a= $0.43
t=37 - take 1980 and subtract it from 2017
r= .063 - the 6.3% goes into a decimal
n = 1
Y= ?
Y= 0.43( 1+ .063/1) ^1*37
Y= 0.43 (1.063) ^37
Y= 4.12
Answer:
Step-by-step explanation:
Given data :
Sample standard deviation, s = 15
Sample mean,
n = 23
a). 98% confidence interval
∴
So, 98% CI is
