Answer: kindly check explanation
Step-by-step explanation:
A.) The population of interest refers to all the entire observations belonging to a certain group or category in a study, hence all vehicles on the road in your hometown is the population of interest in the scenario described above.
B.) Variable of interest refers to what we aim to study, measure or observe in our population or sample, Hence, the variable of Interest is to determine if a certain vehicle is an SUV or NOT
C.) What is the parameter of interest and what symbol should we use to denote it?
The parameter are numeric computations derived from a population. Which is the proportion of SUV's in the population of vehicles in hometown
d. What is the statistic, what symbol should we use to denote it, and what is its value?
Statistic derived from the sample and it is hence the proportion of SUV's that pass the intersection between 7 - 8 am (as the number of vehicles that pass at this time is only a subset of the entire vehicle population).
E.) Yes it is a simple Random sampling, because the number of SUV's or vehicles are entirely by chance.
F.) Given the time of sampling and the fact that SUV's are mostly driven by official workers and parents, the number of SUV's may likely surge at this time due to those leaving for work and kids being dropped at their various schools.
Answer:
A) Reject the null hypothesis and conclude that chocolate affected mood because zero, or no effect, does not fall within the confidence interval
Step-by-step explanation:
The confidence interval could be used as a tool to test an hypothesis on a some certain conditions. When we obtain a confidence interval whose range includes the value 0, we would fail to reject the null hypothesis of such analysis as this upholds the truth of the null hypothesis. However, if the interval does not contain the value 0, we reject the null and claim that there is significant evidence to accept the alternative hypothesis.
Hence, for the confidence interval given [2.34, 5.41], the interval does not contain the value 0, Hence, we reject the null.
Answer:
x=6.5
Step-by-step explanation:
Don't worry I just know
Answer:
Step-by-step explanation:
h = −16(x − 2)² + 72
= −16((x − 2)(x − 2)) + 72 expand the square (x - 2)² = (x - 2)(x - x)
= -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72
= -16 (x² + (-2x) + (-2x) + (4) ) + 72
= -16 (x² + (-4x) + (4) ) + 72
= -16 (x² - 4x + 4 ) + 72
= (-16)(x²) + (-16)(-4x) +(-16)(4) + 72
= -16x² + 64x - 64 + 72
= -16x² + 64x + 8 My guess is D ; 72 ???
I have no clue what the ; 72 means after the given answer. It must be a standard form thing I never learned.
The answer is 22. if it started with 860 and in 8 hours it has 1036 then you would subtract 1036 - 860 which is 176 and that divided by 8 is 22. hope that helps. :)
