Answer:

Step-by-step explanation:

The set of numbers is:

3,9,8,6,3,4,9,2,5,10,8,1

Arranging this set of numbers in the ascending order, we have

1,2,3,3,4,5,6,8,8,9,9,10

The mode is the number which occurs frequently in the set, therefore 3, 8 and 9 are the frequently occurring numbers in the given set, hence there are three modes in total.

The median is the middle number in the given data, since the numbers are even in nature, therefore the median will be the mean of the middle numbers that is:

Median= $\frac{5+6}{2}$ = $\frac{11}{2}$ = $5.5$

Thus,the median is the mean of 5 and 6.

Mean= $\frac{1+2+3+3+4+5+6+8+8+9+9+10}{12}$

= $\frac{68}{12}$

= $5.67$

Thus, mean is greater than the median.

Hence, The given set has three modes, the median is the mean of 5 and 6 and the mean is approximately 5.67.

1,2,3,3,4,5,6,8,8,9,9,10

Median: 7

The mean is smaller han the meidan
The mean is approximately 5.66666667
This set has three modes.

The answer is 34.05

The total distance (D) is the sum of three distances (d1, d2, and d3).

The distance formula is $d = \sqrt{(x2-x1)^{2} +(y2-y1)^{2}}$

Distance 1: Phoenix (–12, –16) to Blythe (–20, –9):
 $d1 = \sqrt{(-20-(-12))^{2} +(-9-(-16))^{2}} =\sqrt{(-20+12)^{2} +(-9+16)^{2}} \\ =\sqrt{(-8)^{2} +(7)^{2}}= \sqrt{64+49} = \sqrt{113}= 10.63$

Distance 2: Blythe (–20, –9) to Los Angeles (–33, –4):
$d2 = \sqrt{(-33-(-20))^{2} +(-4-(-9))^{2}} =\sqrt{(-33+20)^{2} +(-4+9)^{2}} \\ =\sqrt{(-13)^{2} +(5)^{2}}= \sqrt{169+25} = \sqrt{194}= 13.93$

Distance 3: Los Angeles (–33, –4) to San Francisco (–36, 5)
 $d3 = \sqrt{(-36-(-33))^{2} +(5-(-4))^{2}} =\sqrt{(-36+33)^{2} +(5+4)^{2}} \\ =\sqrt{(-3)^{2} +(9)^{2}}= \sqrt{9+81} = \sqrt{90}= 9.49$

D = d1 + d2 + d3 = 10.63 + 13.93 + 9.49 = 34.05

Hello please your question is in-complete attached is the complete question

degree of freedom = -62.90 ( e )

Step-by-step explanation:

The formula for calculating the F-statistic/test statistic is

test - statistic = Coef ( LBW) / SE Coef ( LBW )

= -0.72399 / 0.01151

= - 62.90

the degree of freedom the F-statistic has = -62.90

F-statistic test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. the value of the test can be gotten from running an ANOVA test or regression analysis on the statistical models
