Answer:

Step-by-step explanation:

t2 = a*r

t2 = 6

t5 = a*r^4

t5 = 162

162/6 = ar^4 / ar

r^3 = 27

r = 3

6 = a*3

2 = a

Sum = a(r^n - 1)

           =======

             r - 1

n = 5

a = 2

r = 3

Sum = 2(3^5 - 1)

           =======

               2

Sum = 242

A pediatrician wants to conduct a survey to determine if the number of children per family is statistically the same in the Unit
kari74 [83]

Answer:

<u><em>There is not enough information to know if there is a statistically significant difference in the number of children per family between the three countries.</em></u>

Step-by-step explanation:

There are other important information that are necessary in order to reach a decisive conclusion. This includes not just the f value only, but the alpha value, f critical value and the p-value after conducting the one way ANOVA.

Since we do not have information about the p value, as well as the alpha value there is no way to compare the effects of all the variables.  

Therefore, no decision can be made by the Pediatrician without knowing what the p value is and the apha value is.
