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  

=>    

true? is that what you're asking or do you mean something else?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
