Answer:
Z=11.0
Step-by-step explanation:
Let Caucasian individuals be the population 1 and African American be the population 2. So, we are given that
n=150
n1=75
mean1=xbar1=6.1.
standard deviation1=S.D1=σ1=1.1.
Variance1=V(x1)=σ1²=1.1²=1.21.
n2=75.
mean2=xbar2=4.3.
standard deviation2=S.D2=σ2=0.9.
Variance2=V(x2)=σ2²=0.9²=0.81.
The z-statistic is





Z=10.97
Z=11.0
So, the z value obtained while calculating the test statistic is approximately 11.0.
Answer:
416 (3 s.f.)
Step-by-step explanation:
To multiply decimals, begin by multiplying the numbers as if there is <u>no decimal</u>:

Count the number of digits <u>after</u> the decimal point in each factor:
- 128.5 → 1 digit after the decimal point.
- 3.24 → 2 digits after the decimal point.
Therefore, there is a total of 3 digits after the decimal points.
Put the same number of digits after the decimal point in the product.
Therefore, the solution is to the multiplication is:
The factor with the <u>fewest signification figures</u> is 3.24.
This number has 3 significant figures.
Therefore, the solution to 3 significant figures is:
