Answer: -0.99

Step-by-step explanation:

From the given picture, it can be seen that there is a strong negative correlation between the variables.

i.e. the value of correlation coefficient must be negative.

The value of strong correlation coefficient r, lies between the absolute value of 0.75 to 1.

From all the given options -0.99 has the nearest value to the absolute value of 1.

Therefore, the best estimate of the correlation coefficient for the variables in the scatter plot = -0.99

I believe this would be -.99. Correlation typically goes from -1 to 1 with 0 being no correlation whatsoever. Since this has such a strong negative slope, it would need to be as close to -1 as possible.

A company conducted a survey to see whether its new toothpaste was morepopular with children or adults. Of the children surveyed

Naily [24]

Given: The information provided in the table shown

To Determine: From the options provided, the correct option that best describe the information given in the table

Solution

Given that 28% of the children used toothpaste. From the table

$Children(toothpaste)=\frac{0.07}{0.25}=\frac{7}{25}\times100=28\%$

Let us calculate the percentage of adult that used toothpaste

$Adult(toothpaste)=\frac{0.08}{0.75}=\frac{8}{75}\times100=10.667\%\approx11\%$

Hence, a smaller percentage of adults (about 11%) use the toothpaste.

The correct option is OPTION C
