Select Parameter or Statistic to classify each statement.
Annette [7]

Answer:

1) Statistic

2) Parameter

3) Statistic

4) Parameter.

Step-by-step explanation:

Parameter: is a number that describes the whole population.

Statistic: is a number that describes a sample.

The difference is:

50% of the cats are nice (parameter, because talks about all the cats)

out of 100 cats surveyed, 39 are nice (statistic, because talks about a sample of 100 cats)

Then:

1) 85% of those surveyed were in favor of bike lanes.

This only refers to the surveyed people, so this only refers to a sample (and not the population that this sample represents) then this is a statistic statement.

2) Each member of the soccer team has an average of 2 jerseys.

In this case, we are talking about the whole population (the soccer team) then this is a parameter

3) Of the 100 swim teams surveyed across America, 23 practice 10 hours a week.

Here the information is about the sample (only 100 swim teams). So here the correct option is statistic.

4) The golf team's average score is 79

Here the information is about the average score for the entire golf team, so this information is about all the population in the golf team, then in this case the correct option is parameter.

Data Set #1
Harman [31]

Answer:

The data table is attached below.

Step-by-step explanation:

The average of a set of data is the value that is a representative of the entire data set.

The formula to compute averages is:

\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}

Compute the average for drop 1 as follows:

\bar x_{1}=\frac{1}{3}\times[10+11+9]=10

Compute the average for drop 2 as follows:

\bar x_{2}=\frac{1}{3}\times[29+31+30]=30

Compute the average for drop 3 as follows:

\bar x_{3}=\frac{1}{3}\times[59+58+61]=59.33

Compute the average for drop 4 as follows:

\bar x_{4}=\frac{1}{3}\times[102+100+98]=100

Compute the average for drop 5 as follows:

\bar x_{5}=\frac{1}{3}\times[122+125+127]=124.67

The data table is attached below.

jada goes to get her hair done the cost for a haircut and blowout is 65.42 she leaves a 25% tip for the stylist what is the tota
Art [367]

Answer:

The total cost is $81.78

Step-by-step explanation:

First lets calculate the tip

tip = cost * percent of tip

tip = 65.42*.25

tip = 16.355

Which rounds to 16.36  since we are working with money and round to the nearest cent

total cost = cost of cut and blowout + tip

                = 65.42 +16.36

                     =81.78
