Answer:
The point estimate of the proportion of people over 6ft to total people is 6:25
Step-by-step explanation:
To find this, simply start with the number of people over 6 ft and total people as a proportion.
12:50
Then simplify by dividing by 2
6:25
If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to
.
Remember that an equation
represents a line with slope
and y-intercept
. Since both equations given have a slope of -2, but have different y-intercepts, they are
parallel.
Answer:
0.0416
Step-by-step explanation:
Given :
Sample size, n = 300
Sample mean, x = 35.5
Population mean, m = 35
Standard deviation, s = 5
The test statistic :
Zstatistic = (x - m) / s/sqrt(n)
Zstatistic = (35.5 - 35) / 5/sqrt(300)
Zstatistic = 0.5 / 0.2886751
Zstatistic = 1.732
Using the p value calculator from Zstatistic :
One tailed P value at 95% confidence interval is : 0.0416
