Using the dot plot and statistical concepts, it is found that the correct option is:

Their means will be most affected because this value will be an outlier.

The dot plot shows the <u>number of times each measure appears in the data-set.</u>

In this problem, for both Walter and Janine, the dot plots are cluster between 80 and 90, which means that their grades are in this range.

Hence, for both, a grade of 65 would be an outlier, and the measure that is most affected by outliers is the mean.

Hence, the correct option is:

Their means will be most affected because this value will be an outlier.

Is 0.2487 a interger

BabaBlast [244]

No. 0.2487 is not an interger.

There are two big reasons for this:

1). There is no such thing as an ' interger ',
   so no number could be one.
   You probably mean ' integer '.

2). An integer is a whole number ... a number
    with no fraction part and no decimal part.
    0.2847 is all decimal, and not even big enough
      to make the smallest whole number. (That's ' 1 '.)

For a left-tailed test, the critical value of z so that a hypothesis test would reject the null hypothesis at 1% significance le

mars1129 [50]

Answer:

C.-2.33

Step-by-step explanation:

We are given that

Significance level, $\alpha =1$ %=0.01

We have to find the critical value of z for a left-tailed test.

To find the critical value , we will use the z-table at significance level 0.01 for left-tailed test.

By using the z-table at significance level 0.01 for left-tailed test

The critical value of z at 1% significance level for left-tailed test

=-2.33

We get p-value by using z-critical value

P-value=0.0099<0.01

So, hypothesis test would be reject the null hypothesis at at 1% significance level.

Hence, the critical value of z=-2.33

Option C is true.
