What does it mean if a statistic is resistant? choose the correct answer below.

1 answer:

4 0

When we say a statistic is resistant, we mean the extreme values do not affect the statistic to a large extent or to an extent which makes a major difference. Mean and median are example of such statistics. By changing the extreme values we do not see a substantial difference in the value of mean and median for the data set.

Consider a sample: 1,2,3,4,4,5,6,7,8
The median for this data set is 4.
If we change the extreme values to get this sample: -5,2,3,4,4,5,6,7,100
The median will still be the same i.e. 4. This is what is meant by a resistant statistic.

So option a is the correct ans.

The product of two consecutive positive integers is 56. Find the two integers

vredina [299]

Answer:

Two consecutive integers are of the form

x and x + 1

Their product is equal to 56

x(x + 1) = 56

Solve and find the two numbers x and x + 1. The above equation may be written as follows

x2 + x - 56 = 0

Factor and solve

(x - 7)(x + 8) = 0

solutions: x = 7 , x = -8

x= - 8 is not valid since the number sought must be positive. Hence

x = 7 and x + 1 = 8 are the two consecutive numbers.

Hello!

This is a classic fractions exercise.

The whole brownie was cut in three equal pieces. Each piece represents 1/3 of the brownie.

If you add the three pieces together 1/3+1/3+1/3 you get the whole brownie again 3/3 = 1

-Options-

The whole brownie is 1/3.

<em>The whole brownie is 3/3. </em>

The whole brownie is 2/3.

The whole brownie is 3/2.

I hope this helps!

Write an expression to represent the length of a string in yards in terms of the string's length, x, in inches

Sergio039 [100]

Answer:

$y = \frac{x}{36}$

Step-by-step explanation:

Given

Length of string = x inches

Required

Determine the length in yards

Represent the equivalent length with y

Such that

$y = x\ inches$

Divide x by 36 to get equivalent in yards

$y = \frac{1}{36} * x$

$y = \frac{x}{36}$

Hence, the equivalent in yards is $\frac{x}{36}$

A jar of 50 sour ball candies contains only 3 flavors. If there are 18 orange, 12 lemon, and 20 cherry sour balls, what is the p

Alla [95]

Option B. 12/ 125 is the answer.

Explanation

Total umber of sour ball candies = 50

Number of lemon candies = 12

Hence the probability to get a lemon candy is = 12/50

Number of cherry sour balls = 20

So, the probability to get a cherry sour ball = 20/50

So, to get the joint probability for a random selection to either get a lemon or cherry candy, we will multiply both the probabilities.

$\frac{12}{50}*\frac{20}{50}$

= $\frac{12}{125}$
