The following histogram shows the relative frequencies of the height recorded to the nearest inch of population of women the mean of the population is 64.97 inches and the standard deviation is 2.66 inches
(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work
Answer:
0.22268
Step-by-step explanation:
z-score is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work
At least means equal to or greater than 67 inches
z = 67 - 64.97/2.66
z = 0.76316
P-value from Z-Table:
P(x<67) = 0.77732
P(x>67) = 1 - P(x<67) = 0.22268
The probability that the selected woman will have a height of at least 67 inches is 0.22268
564 (57/24)^2
= 564 · 5.64
= 3,181

Step-by-step explanation:
Given the illustration in the question
Required:
Use deductive reasoning to prove (a)
From your question, you need only the (b) part and this is done as follows;
Step 1: Represent the number with: n
Step 2: Multiply n by 4: 4n
Step 3: Add 10 to (2) above: 4n + 10
Step 4: Divide (3) above by 2: (4n + 10)/2 = 4n/2 + 10/2 = 2n + 5
Step 5: Subtract 5 from (4): 2n + 5 - 5 = n
<em>Hence, the end result is proved to be 2n </em>
<em></em>
<em>Test this with any of the given illustration in (a) part, your answer will always be 2n</em>
