Answer: 4
Step-by-step explanation:
For given Population standard deviation , the formula to sample size is given by :-
, where z* = Two-tailed critical value.
E = Margin of error.
Given : years
We know that , Critical value for 90% confidence interval : z* = 1.645
Margin of error : E=1.3 years
Then, the minimum sample size required to construct a 90% confidence interval for the population mean will be :-
[Rounded to the nearest whole number.]
Hence, the minimum sample size required = 4
Answer:
$9.6
Step-by-step explanation:
The computation of the price of the mixture is shown below:
The price of candy is
= 3 lbs × $1.7 per pound
= $5.1

= 5 × 0.90
= $4.5
So, the total price of the mixture be
= $5.1 + $4.5
= $9.6
