Answer:

0.5

Step-by-step explanation:

First find the mean of the data

3+4+4+5 = 16

16/4 = 4

Find the distance of each data to the mean

4-3 = 1

5-4= 1

4-4 = 0

Now find the mean of those

1+1+0+0 = 2

2/4

MAD = 0.5

Sandy has 27 roses, 9 daisies, and 18 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number

AlekseyPX

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers

Step-by-step explanation:

We solve the above question using Greatest Common Factor method. We find the factors of 27, 9 and 18. The greatest factor common to the 3 number is our answer.

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

The factors of 27 are: 1, 3, 9, 27

Then the greatest common factor is 9.

The greatest number of flowers that could be in a bouquet is 9 flowers

Suppose the heights of 18-year-old men are approximately normally distributed, with mean 65 inches and standard deviation 4 inch

Serhud [2]

Answer:

Step-by-step explanation:

<u>a)</u>

Given that ; X ~ N ( µ = 65 , σ = 4 )

P ( 64 < X < 66 )

From application of normal distribution ;

Z = ( X - µ ) / σ, Z = ( 64 - 65 ) / 4, Z = -0.25

Z = ( 66 - 65 ) / 4, Z = 0.25

Hence, P ( -0.25 < Z < 0.25 ) = P ( 64 < X < 66 ) = P ( Z < 0.25 ) - P ( Z < -0.25 ) P ( 64 < X < 66 ) = 0.5987 - 0.4013

P ( 64 < X < 66 ) = 0.1974

b) X ~ N ( µ = 65 , σ = 4 )

P ( 64 < X < 66 )

From normal distribution application ;

Z = ( X - µ ) / ( σ / √(n)), plugging in the values,

Z = ( 64 - 65 ) / ( 4 / √(12)) = Z = -0.866

Z = ( 66 - 65 ) / ( 4 / √(12)) = Z = 0.866

P ( -0.87 < Z < 0.87 )

P ( 64 < X < 66 ) = P ( Z < 0.87 ) - P ( Z < -0.87 )

P ( 64 < X < 66 ) = 0.8068 - 0.1932

P ( 64 < X < 66 ) = 0.6135

c) From the values gotten for (a) and (b), it is indicative that the probability in part (b) is much higher because the standard deviation is smaller for the x distribution.
