Answer:

Step-by-step explanation:

1. Regroup terms.

y+3=9−y

2. Subtract 33 from both sides.

y=9-y-3y=9−y−3

3. Simplify 9-y-39−y−3 to 6-y6−y.

y=6-yy=6−y

4. Add yy to both sides.

y+y=6y+y=6

5. Simplify y+yy+y to 2y2y.

2y=62y=6

6. Divide both sides by 22.

y = 6/2

7. Divide

y = 3

If you have 66 data observations in a sample, how many classes (bins) does the sturges' rule recommend for you to construct a fr

Iteru [2.4K]

According to Sturge's rule, number of classes or bins recommended to construct a frequency distribution is k ≈ 7

Sturge's Rule: There are no hard and fast guidelines for the size of a class interval or bin when building a frequency distribution table. However, Sturge's rule offers advice on how many intervals one can make if one is genuinely unable to choose a class width. Sturge's rule advises that the class interval number be for a set of n observations.

Given,

n = 66

We know that,

According to Sturge's rule, the optimal number of class intervals can be determined by using the equation:

$k=1+log_{2} n$
