To be able to determine the type of skew exhibited by the distribution of the heights he achieved in each of his attempt we arrange the distribution in order and obtain the frequency of each data in the distribution. Height (meters): 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 Frequency: 2, 1, 1, 2, 2, 3, 1, 2, 1, 1, 1, 1, 1, 1 Calculating the mean gives (11 x 2 + 12 + 13 + 14 x 2 + 15 x 2 + 16 x 3 + 17 + 18 x 2 + 19 + 20 + 21 + 22 + 23 + 24) / 20 = 335 / 20 = 16.75 Since there are more higher frequencies to the left of the mean we conclude that the distribution exhibits a positive skew.

Suppose the average height of all humans is normally distributed with a mean of 72 inches and a variance of 18 inches.

nignag [31]

Answer:

a) P(75 < x < 80 ) = 0.2088

b) The probability that average height of all humans less than 65

P( X < 65 ) = 0.0495

Step-by-step explanation:

Step(i):-

Given mean of the Population = 72

Given variance of the Population = 18 inches.

Standard deviation of the Population = √18 = 4.242

Let 'x' be the random variable in Normal distribution

Given X₁ = 75

$Z_{1} = \frac{x_{1} -mean}{S.D} = \frac{75-72}{4.242} = 0.70721$

Given X₂= 80

$Z_{2} = \frac{x_{2} -mean}{S.D} = \frac{80-72}{4.242} = 1.885$

The probability that average height of all humans between 75 and 80

$P(75 < X < 80 ) = P(0.70721 < Z < 1.885)$

= | A ( 1.885) - A( 0.70721|

= 0.4699 - 0.2611

= 0.2088

P(75 < x < 80 ) = 0.2088

Step(ii):-

Given X₁ = 65

$Z_{1} = \frac{x_{1} -mean}{S.D} = \frac{65-72}{4.242} = -1.650$

The probability that average height of all humans less than 65

P( X < 65 ) = P( Z < - 1.650 )

= 1 - P( Z > 1.650)

= 1 - ( 0.5 + A (1.650))

= 0.5 - A( 1.65)

= 0.5 - 0.4505

= 0.0495

The probability that average height of all humans less than 65

P( X < 65 ) = 0.0495

Meg initially has 3 hours of pop music and 2 hours of classical music in her collection. Every month onwards, the hours of pop m

zlopas [31]

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Number of hours of pop music = 3

Number of hours of classical music = 2

According to question, Every month onwards, the hours of pop music in her collection is 5% more than what she had the previous month. Her classical music does not change.

Rate of increment = 5% = 0.05

Let the number of months be 'x'.

So, our required function becomes,

$f(x)=3(1+0.05)x+2\\\\f(x)=3(1.05)x+2$

Hence, Option 'd' is correct.
