Siloni computed in a two-way table the relative frequencies of boys’ and girls’ participation in school sports at her school. school sports participation by gender fall spring boys 37% 57% girls 63% 43% which statement best describes the relationship between the two variables? there is an association because the relative frequencies by column are different. there is an association because the relative frequencies by row are different. there is no association because the relative frequencies by column are different. there is no association because the relative frequencies by row are different.

Sports        Boys            Girls              Total

Fall               37 %             63%              100%

Spring           57%               43%              100%

Formula for relative Frequency

Two Values in the row adds to 100%.

Sum of boys and girls in any row in any Sport adds to 100.

So, Option A,  best describes the relationship between the two variables, which is :

There is an association because the relative frequencies by column are different.  

answer: 4

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
