Suppose, in fact, the mean annual consumption of popcorn after the marketing campaign is 58 58 quarts. has a type i or type ii error been made by the marketing department? if we tested this hypothesis at the alpha α equals = 0.01 0.01 level of significance, what is the probability of committing this error? select the correct choice below and fill in the answer box within your choice.

i believe the answer is 323 ft

step-by-step explanation:

what is the figure? attach a picture.

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
