What are the 1st and 3rd quartiles?<br> what is the interquartile range?
FrozenT [24]

Answer:

The first quartile is 5

The third is 8

The interquartile is the difference between the first and third quartile.

The interquartile is 3

Step-by-step explanation:

First, make a list of all the numbers. To find the first quartile, you have to first find the median. The median is the first 7 in the list.

Everything before 7 is the lower percentile of the range.

The firsr quartile is the median of the lower percentile.

The lower list is:

2,3,4,4,5,6,6,6

The median of this list is 5.

The process for finding the third quartile is the same except the list is the higher percentile which is the list of numbers above the median.

Kisachek [45]

Answer: 2/3

Explanation: Assume that the number of smarties he picked is c.

Now, we are given that:

1- He picked 3 times as many cola bottles as smarties. This means that:

Number of cola bottles he picked = 3s

2- He picked twice as many smarties as marshmallows. This means that:

number of marshmallows he picked = 0.5s

Now to get the proportion o f cola bottles, we will divide the number of cola bottles by the total number of sweets as follows:

proportion of cola bottles =  

Hope this helps :)

For 50 randomly selected speed​ dates, attractiveness ratings by males of their female date partners​ (x) are recorded along wit
Anni [7]

This question is incomplete, the complete question is;

For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10.

The 50 paired ratings yield x = 6.3, y = 6.0, r = -0.194, P-value = 0.176, and y^ = 7.40 - 0.218x.

Find the best predicted value of ​(attractiveness rating by female of​ male) for a date in which the attractiveness rating by the male of the female is x.

Use a significance level.

the best predicted value of y^ when x=8 is ?

( round your answer to one decimal place as needed.

Answer:

The best predicted value of y ^ when x equals 8 is 5.7

Step-by-step explanation:

From the information it is clear that equation for the regression line is

y^ = 7.40 - 0.218x.

where y^ represents the attractiveness rating by female of male partners and  x represents the attractiveness rating by male of female partners.

The predicted value of y ^  when x equals 8 is obtained by substituting the value of x with 8 in the given regression equation.

The predicted value of y^  when x equals 8 is obtained below:;

The regression equation is y^ = 7.40 - 0.218x  

Substitute x = 8x=8

y^  =7.40 − 0.218x

=7.40 − 0.218(8)

=7.40 − 1.744

= 5.656  ≃ 5.7

therefore The best predicted value of y ^ when x equals 8 is 5.7
