B.
Mean: 208.08
Median: 224.4
Mode: 122.4
Range: 183.6
First, we can make it easier by rearranging them from least to greatest in proper numerical form.
$120, $120, $220, $260, $300
Mean: (120 + 120 + 220+ 260 + 300)(1/5)=1020
1020 x 1.02( tax rate) = 1040.4
1040.4/5= 208.08
Median: %220 x 1.02= 224.4
Mode: 120 x 1.02 = 122.4
Range: (300 x 1.02)-(120 x 1.02)= 306-122.4
306 - 122.4 = 183.6
Answer:
Step-by-step explanation:
we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = variable
µ = mean output
σ = standard deviation
From the information given,
µ = 14
σ = 3
1) P(x < 20)
For x = 20,
z = (20 - 14)/3 = 2
From the normal distribution table, the corresponding probability value is 0.98
% = 0.98 × 100 = 98%
2) P(11 ≤ x ≤ 17)
For x = 11,
z = (11 - 14)/3 = - 1
From the normal distribution table, the corresponding probability value is 0.16
For x = 17,
z = (17 - 14)/3 = 1
From the normal distribution table, the corresponding probability value is 0.84
P(11 ≤ x ≤ 17) = 0.84 - 0.16 = 0.68
% = 0.68 × 100 = 68%
3) P(x > 14) = 1 - P(x ≤ 14)
For x = 14,
z = (14 - 14)/3 = 0
From the normal distribution table, the corresponding probability value is 0.5
P(x > 14) = 1 - 0.5 = 0.5
% = 0.5 × 100 = 50%
4) P(5 ≤ x ≤ 17)
For x = 5,
z = (5 - 14)/3 = - 3
From the normal distribution table, the corresponding probability value is 0.00135
For x = 17,
z = (17 - 14)/3 = 1
From the normal distribution table, the corresponding probability value is 0.84
P(5 ≤ x ≤ 17) = 0.84 - 0.00135 = 0.839
% = 0.839 × 100 = 83.9%
Answer:
98.1, No does not contain, yes contains.
Step-by-step explanation:
Given that
sample size n =103
Sample mean = 98.1
sample std dev s = 0.56
a) the best point estimate of the mean body temperature of all healthy humans = sample mean =98.1
b) 99% confidence interval estimate of the mean body temperature of all healthy humans
We can use Z critical since sample size is large though sigma is not known
99% CI = 
This does not contain 98.6
This sample does not represent the population, i.e. may be biased sample.
c) CI of population mean
= populaiton mean + /- margin of error
=(98.545, 98.656)
Yes contains 98.6
Answer:
27 muffins.
Step-by-step explanation:
We have been given that a baker made 60 muffins for a cafe. By noon, 45% of the muffins were sold.
To find the number of muffins sold by noon let us find 45% of 60.
Therefore, 27 muffins were sold by noon.
<h3>
Answers: C) 4.5 m, D) 3.92 m, E) 3.5 m</h3>
Work Shown:
Convert from feet to meters.
15 feet = (15 ft)*(0.3048 m/1 ft)
15 feet = (15*0.3048) meters
15 feet = 4.572 meters approximately
From this point onward, we select all answer choices that are less than 4.572 meters. Those would be C, D and E.
