The essay lengths of 29 randomly sampled essays are used to estimate the mean of the population. What t-score should be used to
1 answer:
Answer:
A t-score of 1.701 should be used to find the 95% confidence interval for the population mean
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 29 - 1 = 28
Now, we have to find a value of T, which is found looking at the t table, with 28 degrees of freedom(y-axis) and a confidence level of 0.95(). So we have T = 1.701.
A t-score of 1.701 should be used to find the 95% confidence interval for the population mean

Step-by-step explanation:
Given expression is:
First we need to find the GCF(Greatest common factor) of and
and then we will factor out that GCF.
We can see that the common factors are:
So, the GCF will be:
Now factoring out from the given expression, we will get.....
So, the complete factorization will be:
Answer: Area of rectangle can be given by expressions:
Step-by-step explanation:
Given : A square has sides of length s.
According to the question,
Dimensions of new rectangles=(s-6)×(s+1)
Thus, Area of rectangle= (s-6)×(s+1)
Thus , area of rectangle can be given by expressions:
