Answer:

3.8*10^1

Step-by-step explanation:

So we'll be using PEMDAS, which is an acronym used to explain order of operations. It stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.

P- Parentheses:

(2x3+4x2+3)+(3x3−(3x−4))

M- Multiplication (within Parentheses):

(6+8+3)+(9−(-12))

A- Addition (within Parentheses):

(6+8+3)+(9−(-12))

17 + 21

A- Addition:

38

Now, we'll take that number and put it in standard form, which is the number with only one number outside of the decimal times ten to the however many times it can be divided by ten.

So,

38/10 = 3.8

So,

3.8 * 10^1 is your answer.

The U.S. Department of Transportation provides the number of miles that residents of the75 largest metropolitan areas travel per
Leya [2.2K]

Answer:

a. The point estimate of the difference between the mean number of miles that Buffalo residents travel per day and the mean number of miles that Boston residentstravel per day is 88

b. The 95% confidence interval for the difference between the two population means is (0.58171,7.21829)

Step-by-step explanation:

a. According to the given data we have the following:

Buffalo residents mean=22.5

Standard deviation=8.4

n=50

Boston residents mean=18.6

Standard deviation=7.4

n=40

Hence, the point estimate is the difference of the means=22.5-18.6=3.9

The standard error=√((s1∧2/n1)+((s2∧2/n2))=√((8.4∧2/50)+(7.4∧2/40))=1.67

Therefore, the difference of miles=n1+n2-2=50+40-2=88

The point estimate of the difference between the mean number of miles that Buffalo residents travel per day and the mean number of miles that Boston residentstravel per day is 88.

b. The critical value of t at 95% confidence level and DoF=88 is 1.987

The interval:(x1-x2)+ (critical value* std error)

=3.9-(1.987*1.67),3.9+(1.987*1.67)

Difference between mean=(0.58171,7.21829)

The 95% confidence interval for the difference between the two population means is (0.58171,7.21829)
