Answer:
[0.4979, 0.5479]
Step-by-step explanation:
-We first determine the sample proportion:
-The confidence intervals of a sample proportion is calculated using the formula:
#We substitute for the sample proportion and z value to get the Confidence interval:
![CI=\hat p\pm z\sqrt{\frac{\hat p(1-\hat p}{n}}\\\\=0.5238\pm 1.645\times \sqrt{\frac{0.5238\times0.4762}{1008}}\\\\=0.5238\pm0.0259\\\\=[0.4979,0.5497]](https://tex.z-dn.net/?f=CI%3D%5Chat%20p%5Cpm%20z%5Csqrt%7B%5Cfrac%7B%5Chat%20p%281-%5Chat%20p%7D%7Bn%7D%7D%5C%5C%5C%5C%3D0.5238%5Cpm%201.645%5Ctimes%20%5Csqrt%7B%5Cfrac%7B0.5238%5Ctimes0.4762%7D%7B1008%7D%7D%5C%5C%5C%5C%3D0.5238%5Cpm0.0259%5C%5C%5C%5C%3D%5B0.4979%2C0.5497%5D)
Hence, the 90% confidence intervals is [0.4979,0.5479]
Answer:
14.29%
Step-by-step explanation:
Let's do the count for Test #1:
2 + 5 + 6 + 1 = 14 total students
Out of which, below 70 is 2 people [only the leftmost bar]
Let's do the count for Test #2:
2 + 3 + 5 + 4 = 14 total students
Out of which, below 70 is again 2 people [only the leftmost bar]
So, to find percentage of people below 70, we divide the below 70 number of people with total number of people.
(2+2)/(14+14) = 4/28 = 14.29%
Given:
The product of 
and 
greater than 5.
To find:
By how much the product of and greater than 5.
Solution:
First we need to find the product of and .
Now subtract 5 from the product.
Therefore, the product of and is 9.85 greater than 5.
Answer:
Length of prism = 17.5 in
Step-by-step explanation:
Given:
Width = 16 in
Height = = 3.75 in
Volume of rectangular prism = 1,050 inches
Find:
Length of prism
Computation:
Volume of rectangular prism = WHL
1,050 = Length of prism × 16 × 3.75
Length of prism = 17.5 in
