The  99% confidence interval is  

Step-by-step explanation:

From the question we are told that

   The data is   3, 2,5, 3, 2, 6, 5,4.5, 3, 3, and 4

    The sample size is  n  =  11

Generally the sample mean is mathematically represented as

=>  

=>  

Generally the sample standard deviation  is mathematically represented as

=>  

=>  

Given that the confidence interval is 99% then the level of significance is mathematically represented as

=>      

Given  that the sample size is small we will making use of t distribution table  

Generally from the t distribution table the critical value  of   at a degree of freedom of  is  

Generally the margin of error is mathematically represented as  

Generally 99% confidence interval is mathematically represented as  

=>    

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

the correct option is b
