Answer:
No. I don't have enough Flour to make 5 loaves of bread.
From the Amount of flour i had i can make 4 loaves only.
Step-by-step explanation:
Given:
Flour required for making loaves of bread = 
cups
Amount of flour i had = 8 cups
Number of loaves of bread = 
We need to find the we have enough flour to make 5 loafs of bread.
Solution:
We know that;
Amount of flour I had is equal to Flour required for making loaves of bread
framing in equation form we get;
Dividing both side by 2 we get;
Hence From the Amount of flour i had i can make 4 loaves only.
Hence I don't have enough Flour to make 5 loaves of bread.
Answer:
The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 62 - 2.08 = 59.92
The upper end of the interval is the sample mean added to M. So it is 62 + 2.08 = 64.08.
The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.
