Answer:
99% Confidence interval: (50.9,61.3)
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= 56.1
Sample size, n = 72
Alpha, α = 0.01
Sample standard deviation, σ = 16.7
Degree of freedom = n - 1 = 71
99% Confidence interval:
Putting the values, we get,
<span>f(x)=<span>x2</span>−1</span>That means to find the value of the function at any value of x, we square x and subtract 1. If <span>x=2a</span>, we square <span>2a</span> and subtract 1:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1</span>Now, we know that <span>f(2a)=35</span>so we can find the value of a:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1=35</span><span>4<span>a2</span>−1+1=35+1</span><span>4<span>a2</span>=36</span><span><span>a2</span>=9</span><span><span>a=±3</span></span>
