It there sufficient evidence to conclude that more than 75% of US businesses monitor employees web site visits? Test the appropriate hypotheses using a significance level of 0.01
Answers
Complete question is;
In a survey of 565 U.S. businesses, 430 of these companies indicated that they monitor employees' web site visits. For purposes of this exercise, assume that it is reasonable to regard this sample as representative of businesses in the United States.
Is there sufficient evidence to conclude that more than 75% of U.S. businesses monitor employees' web site visits? Test the appropriate hypotheses using a significance level of 0.01. (Round your test statistic to two decimal places and your P-value to four decimal places.)
Answer:
There's not sufficient evidence to suggest that more than 75% of U.S. businesses monitor employees website visits.
Step-by-step explanation:
Population proportion; p^ = 430/565 = 0.761
Sample proportion; p = 75% = 0.75
Significance level; α = 0.01
Sample size; n = 560
Let's define the hypotheses;
Null hypothesis; H0: p = 0.75
Alternative hypothesis: p > 0.75
Formula for the test statistic is;
z = (p^ - p)/√[p^(1 - p^)/n]
z = (0.75 - 0.761)/√(0.75(1 - 0.75)/560)
z = -0.011/√0.00033482143
z = -0.011/0.0183
z = -0.60
From online p-value from z-score calculator attached, using; z = -0.60, significance level = 0.01, one tailed hypothesis, we have;
P-value ≈ 0.2743
The p-value is greater than the significance level and so we will fail to reject the null hypothesis and conclude that there's not sufficient evidence to suggest that more than 75% of U.S. businesses monitor employees website visits.

A nutrition label on a can of tuna fish states that every 1/4 cup of tuna has 1/2 gram of fat. How many cups of tuna are there for every gram of fat?
Answers
Answer: 1/2 cups
Step-by-step explanation:
Given that:
Every 1/4 cup of tuna has 1/2 gram of fat
How many cups of tuna are there for every gram of fat:
Let cup of tuna for 1 gram of fat = t
Hence, If
1/4 cup of tuna = 1/2 cup of fat
t tuna = 1 cup of fat
Cross multiply :
1/2 t = (1/4 * 1)
1/2 t = 1/4
t = 1/4 ÷ 1/2
t = 1/4 * 2/1
t = 2/4
t = 1/2
Hence, 1/2 cups of tuna for every gram of fat

y = (x - 6)(x + 1)
Step-by-step explanation:
Use factored form, y = a(x - r1)(x - r2), where r1 and r2 are roots.
Since the solutions are 6 and -1, plug in these numbers:
y = (x - 6)(x + 1)
So, the factored equation is y = (x - 6)(x + 1)

Shoppers at a grand opening for a sporting goods store receive a gift bag when they make a purchase. How often will a bag contain both a T-shirt and socks? Items in the Gift Bag T-shirt Every 4th bag Socks Every 3rd bag
Answers
Answer:
Every 12th bag
Step-by-step explanation:
Given that:
Gift bag contains :
T - shirt = every 4th bag
Socks = Every 3rd bag
To obtain how often gift bag contains both T-shirt and socks , obtain the Lowest common multiple of 4 and 3
Multiples of :
4 : 4, 8, 12, 16, 20, 24,....
3 : 3, 6, 9, 12, 15, 18, 21, 24,....
Hence, the lowest common multiple of both 4 and 3 is 12.
The bag will contain both T-shirt and socks after every 12th bag

A local zoo has two large snakes. The anaconda is currently 5.23 meters long and grows 1.27 meters every month. The python is 4.76 meters long and grows 2.04 meters per month. How many months (m) does the zookeeper need to wait for the two snakes to be the same length?
Answers
Answer:
1 months
Step-by-step explanation:
Given
Anaconda
[tex]Length = 5.23m[/tex]
[tex]Growth = 1.27m[/tex] monthly
Python:
[tex]Length = 4.76m[/tex]
[tex]Growth = 2.04m[/tex] monthly
Required
Determine when their length will be equal
First, we need to write equations that determines the growth of each snake in m months.
For both snakes;
[tex]Expression = Length + Growth * m[/tex]
For the Anaconda, the expression is:
[tex]5.23 + 1.27 * m[/tex]
[tex]5.23 + 1.27 m[/tex] --- (1)
For the Python, the expression is
[tex]4.76 + 2.04 * m[/tex]
[tex]4.76 + 2.04m[/tex] ---- (2)
Both snakes will have equal length when both expressions (1 & 2) are equal
[tex]4.76 + 2.04m = 5.23 + 1.27 m[/tex]
Collect Like Terms
[tex]2.04m - 1.27 m= 5.23 - 4.76[/tex]
[tex]0.77 m= 0.47[/tex]
Solve for m
[tex]m = \frac{0.47}{0.77}[/tex]
[tex]m = 0.61[/tex]
[tex]m = 1[/tex] --- Approximated
Hence, the zookeeper will wait for 1 month
Rectangle ABCD is shown on the grid. What is the area of rectangle ABCD in square units? square units square units 17 square units 34 square units
Answers
Answer:
34sq. units
Step-by-step explanation:
The area of the rectangle shown is expressed as;
A = length *width
The length = AD = BC
Width = AB = CD
From the diagram, we will look for AD and AB using the formula for calculating distance between two points;
D = √(x2-x1)²+(y2-y1)²
For AB where A(-1,4) and B(3,3)
AB = √(3-(-1))²+(3-4)²
AB = √(4)²+(-1)²
AB =√16+1
AB = √17
For AD where A(-1,4) and D(-3,-4)
AD = √(-3-(-1))²+(-4-4)²
AD = √(-2)²+(-8)²
AD =√4+64
AD = √68
Hence area of the rectangle = √17*√68
Hence area of the rectangle = √1156
Hence area of the rectangle = 34
Hence area of the rectangle ≈ 34sq. units
