Time spent babysitting by Lucy = Tl = 4 hours

Time spent babysitting by Maria = Tm = x * 4 hours

Now we need to determine for what values of x is Tm > Tl

⇒ x * 4 > 4

⇒ x > 1

So for x > 1, Mary spends more time babysitting than Lucy does

Answer:

\hat p =\frac{26}{39}=0.667

Step-by-step explanation:

Some important concepts

A proportion refers to "the fraction of the total that possesses a certain attribute"

The data det ordered from the smallest to the largest value is:

3.1 ,3.71 ,3.71 ,3.74 ,3.98 ,3.98 ,4.15 ,4.16 ,4.16 ,4.32 ,4.34 ,4.51 ,4.51 ,4.56 ,4.57 ,4.57 ,4.57 ,4.61 ,4.62 ,4.63 ,4.64 ,4.64 ,4.64 ,4.64 ,4.86 ,4.96 ,5.04 ,5.11 ,5.12 ,5.37 ,5.37 ,5.38 ,5.39 ,5.47 ,5.48 ,5.62, 5.65 ,5.65 ,5.7

If we are interesed on the sample values below 5.0 we need to count how many values are below this number. If we do this we got that 26 numbers are below 5.0 and the total of numbers are 39.

so the proportion on this case would be"

\hat p =\frac{26}{39}=0.667
