A research report from an independent-measures study states that there are significant differences between treatments, F(3, 48)
Flura [38]

Answer:

k = 4 ;

N = 52

Step-by-step explanation:

Given the ratio F(3, 48)

F takes in degree of freedom values; degree of freedom of groups ; degree of freedom of error

Hence,

df group or treatment = 3

df error = 48

df treatment = k - 1

k = Number of groups

3 = k - 1

3 + 1 = k - 1 + 1

4 = k

Number of treatment condition = 4

df error = N-k

N = total number of observations

48 = N - 4

48 + 4 = N - 4 + 4

52 = N

On a set of blueprints, the length of a building is 16 inches. The actual building is 85 1/3 feet long. Which of the following i
dusya [7]

Answer:

1 : 64

Step-by-step explanation:

We require the dimensions to be the same units

1 foot = 12 inches , then

85 \frac{1}{3} feet = \frac{256}{3} × 12 = 256 × 4 = 1024 inches

Scale is then

16 in : 1024 in ( divide both parts by 16 )

= 1 : 64

devlian [24]

Answer: 53

Step-by-step explanation:

The original square had a dimension of x and x was reduced by 2 which means x-2 and 3 was added so the formula will be x-2+3=54 and to work that out you have to do it backwards.

54-3=51

51+2=53

So the original dimension was 53inches
