The answer is - balalalalalalalalalak you should figure it out
Answer:
i) 
And replacing we got:
ii) 
Step-by-step explanation:
Notation and definitions
number of people that claimed always buckle up.
random sample taken
estimated proportion of people that claimed always buckle up
true population proportion of people that claimed always buckle up
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The population proportion have the following distribution
Solution to the problem
Part i
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by 
and 
. And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
The margin of error is given by:
And replacing we got:
Part ii
And the confidence interval would be given by:

Answer:
5 represent calories from other ingredients
c= 5 1/2 grams
Step-by-step explanation:
Total calories=c grams of carbohydrates + other ingredients
Total calories in granola bite=27
The equation 4c + 5 = 27 represents the relationship between these quantities
1. 5 represent calories from other ingredients
2. Priya said that neither 8 nor 3 could be the solution to the equation
4c + 5 = 27
When the solution is 8
4(8)+5=27
32+5=27
37 =27
Solution 8 gives a higher calories than total calories
When solution is 3
4(3)+5=27
12+5=27
17=27
Solution 3 gives a lower calories than total calories
3. Solution to the equation
4c + 5 = 27
Subtract 5 from both sides
4c+5-5=27-5
4c=22
Divide both sides by 4
c=22/4
=5 2/4
=5 1/2
c= 5 1/2 grams
Answer:
5
Step-by-step explanation:
To answer this, we must figure out the minimum amount we can add 32 to itself to reach 150. This means that we must multiply 32 by our desired amount, x, to reach the amount of hours closest to 150 (but above/equal to it). To find x, we can divide 150 by 32, and if it gives us a number with no decimals or remainders, that is x, as it is the smallest amount of people to get above/equal to 150. If it gives us a remainder/decimal, we must round up, as we cannot have a part of a person and we must get the work done, so we must get at least 150 hours. 150/32 is 4.6 something, so we must round up. 5 is our answer
