Answer: a) 84 and b ) 2084
Step-by-step explanation:
Given : Sample standard deviation : s= $22.82
(Population standard deviation is unknown ) , so we use t-test.
Critical value or the 95% confidence intervals :
Formula to find the sample size :
a) E = 5
i.e. Required sample size : n= 84
b) E = 1
i.e. Required sample size : n= 2084
<h2>Hello!</h2>
The answer is:
The fabric will cost $4.58
D.$4.58
<h2>Why?</h2>Since it's a conversion exercise, we need to pay special attention to the conversion procedure.
From the statement we know that:
So, if she needs 10 feet of fabric, we need to convert it to meters, and then, calculate its cost.
We have that:
Now, we have that each meter of fabric cost $1.50, so, 3.05m of fabric will cost:
Hence, we have that the cost of the fabric will be $4.58.
The correct option is: D.$4.58
Have a nice day!
