Answer:

The correct answer is wins and rebounds are correlated positively ,but we cannot decided that having more rebounds leads to more wins,on average.

Step-by-step explanation:

From the example given, the most appropriate conclusion is that, because  causation is not the same as correlation, If two variables are compared,this does not mean that one leads to the other.

An observed data is based on correlation,but for description of  causation ,we need to make experiments,as we update the  variable treatment regarding  to the changes in response variable.

The president of a bowling league wanted to estimate the average highest bowling score of all its 200 members. Instead of survey
Nikolay [14]

Answer:


Step-by-step explanation:

In statistics, whenever full population cannot be surveyed, a random sample can be taken and from the observations population behaviour can be estimated.

Here given that there are 200 members.  Instead of collecting data from all 200, 20 members are randomly taken.

The sample mean x bar can be estimated to give an idea the population mean also.

ACcording to central value theorem, means of different samples will follow a distribution with mean = population mean and std deviation = std dev of sample/square root of n

Hence we fix confidence interval as Mean + or - Z critical * std error

This gives us an idea about within which means will lie for different samples and hence give an idea about population mean also.

D. -1 7. A weaver bought a bundle of grass for $50.00 from which he made 8 mats. If each mat was sold for $ 15.00, find the perc
madam [21]

Profit percentage for weaver after selling mat is equals to 140%.

<h3>What is percentage ?</h3>

" Percentage is defined as the hundredth part of the whole given quantity. It is represented by symbol %."

Formula used

Profit% = (\frac{Profit }{cost price} )×   100

According to the question,

Given,

Cost price of bundle of grass = $50.00

Number of mats made = 8

Selling price of each mat = $15.00

Therefore,

Selling price of 8 mats = 15 × 8

                                     = $120

Selling price > Cost price

Therefore,

Profit = Selling price - Cost price

         = 120 - 50

         = $70

Substitute the value in the formula to get profit percentage we get,

Profit% = \frac{70}{50} ×100

            = 140%

Hence, profit percentage for weaver after selling mat is equals to 140%.
