Answer:
Step-by-step explanation:
Given that a study found that the average stopping distance of a school bus traveling 50 mph was 264 feet.
Sample taken showed the following results
Since population std deviation is known and sample size is large, z test can be used.
(Left tailed test)
Mean difference =
Std error =
Z = test statistic = mean diff/std error
=
p value = 0.00017
Since p < alpha our 0.05 we reject null hypothesis
There is evidence to show that mean is less than 264 feet
(Assumptions:
Sample are randomly drawn
Sample represents the population
Answer:
The squared form is not a correct form of the quadratic function.
Step-by-step explanation:
Given some forms of quadratic equation. we have to choose the form which is not correct of the quadratic equation.
As the general form and the standard form of quadratic equation is
where a,b and c are constant.
Also, the vertex form is
where (a,b) is vertex.
Only the three forms of quadratic equation exist. No other form like squared form exist.
Hence, the squared form is not a correct form of the quadratic function.
