Answer:
Standard error = 0.070
Step-by-step explanation:
Formula for the standard error of the distribution of differences in sample proportions is;
σ_(A - B) = √((p_a^(1 - p_a^)/n_a) + (p_b^(1 - p_b^)/n_b))
We are given;
p_a^ = 0.48
n_a = 80
p_b^ = 0.13
n_b = 66
Thus;
σ_(A - B) = √((0.48(1 - 0.48)/80) + (0.14(1 - 0.13)/66))
σ_(A - B) = √0.00496545455
σ_(A - B) = 0.070
Answer:
-4
Step-by-step explanation:
Hey there!
if i am doing this correct it should be
17/50, let me explain!
.34 is 34/100 and both of these numbers are even, thus you can divide it by 2 which will give you 17/50
Hope This Helps!!!
