Um what? There is no table or anything to go off of.
Answer:
Check Explanation
Step-by-step explanation:
a) Confidence Interval for the population mean is basically an interval of range of values where the true population mean can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample mean) ± (Margin of error)
With p(japan) representing the true population proportion of US automobile that are made in Japan, the computer output 90% confidence
0.29938661 < p(japan) < 0.46984416
mean that p(japan); the true population proportion of US automobile that are made in Japan lies within the range of proportions (0.29938661, 0.46984416) with an assurance level of 90%.
b) 90% confidence mean that the true proportion may or may not be in the given range, but we are 90% certain that it does.
c) The confidence interval contradicts the politician's claim that "Half of all cars in the United States are made in Japan" because the proportion in the politician's claim, (0.50), does not lie within the range of values that our confidence interval says the true population proportion can take on; (0.29938661, 0.46984416).
0.50 lies outside of the confidence interval obtained for the true population proportion of US automobiles that are made in Japan, hence, the confidence interval contradicts the politician's claim.
Hope this Helps!!!
Thats the question im sorry if i said it wrong
By answering the questions in your head its simple
Answer:
The correct answer is A. 4/21.
Step-by-step explanation:
Given that Leo hiked 6/7 of a kilometer, while Jericho hiked 2/3 kilometers, to determine who covered a longer distance and how much longer it was, the following calculation must be performed:
Common multiple of 7 and 3 = 21
6/7 = 18/21
2/3 = 14/21
18 -14 = 4
Thus, Leo hiked a longer distance, hiking 4/21 km more than Jericho.
