Answer:
The sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country.
Step-by-step explanation:
In this case we have to perform a hypothesis test on a proportion.
The null and alternative hypothesis are:
The level of significance is 0.1.
The standard deviation for the proportion can be calculated as:
The proportion of the sample is
The test statistic is
The one-tail P-value for z=2.421 is .
The P-value is smaller than the significance level, so the effect is significant.
The null hypothesis is rejected: the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country.
I know it is going to be a really long answer but here is the answer:
Simplifying
6x + 8y + -6z = 62
Solving
6x + 8y + -6z = 62
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation.
6x + 8y + -8y + -6z = 62 + -8y
Combine like terms: 8y + -8y = 0
6x + 0 + -6z = 62 + -8y
6x + -6z = 62 + -8y
Add '6z' to each side of the equation.
6x + -6z + 6z = 62 + -8y + 6z
Combine like terms: -6z + 6z = 0
6x + 0 = 62 + -8y + 6z
6x = 62 + -8y + 6z
Divide each side by '6'.
x = 10.33333333 + -1.333333333y + z
Simplifying
x = 10.33333333 + -1.333333333y + z
