Answer:
Step-by-step explanation:
for the last problem 5-16 are the same go to the hundredths the second decimal from the point and if higher than 5 raise the number by +1 if 4 or lower keep it the same
5/ since 9 is greater than 5 raise the 0 to a 1
You don't you just round it so 0.7 would be 1 but, if it was lower than 0.5 than you just divide it by 2.
Answer:
There is 95% confidence that the true proportion of people who say that a car is a necessity lies in the interval (0.83, 0.89).
Step-by-step explanation:
A (1 - <em>α</em>)% confidence interval for population proportion is given by:

The sample size is, <em>n</em> = 1483.
The 95% confidence interval for the population proportion of people who say that a car is a necessity is,
<em>CI</em> = (0.83, 0.89)
A (1 - <em>α</em>)% confidence interval for a population parameter implies that there is (1 - <em>α</em>) probability that the true parameter value is contained in the interval.
Or, there is (1 - <em>α</em>)% confidence that the confidence interval consists of the true population parameter value.
The 95% confidence interval for the population proportion of people who say that a car is a necessity implies that the true proportion of people who say that a car is a necessity lies in the interval (0.83, 0.89) with a probability of 0.95.
Or, there is 95% confidence that the true proportion of people who say that a car is a necessity lies in the interval (0.83, 0.89).
The length of the vine wounded to the tree is 21 feet.
<h3>How to solve circumference?</h3>
Circumference is the perimeter of a circular object. Therefore,
circumference = 2πr
where
The circumference of the tree is 3 feet. A vine was wound around 7 times .
The length of the vine can be calculated as follows:
Therefore,
circumference = 3 ft
length of the vine = 7 × 3
length of the vine = 21 feet
