Suppose mybook sent out 950 surveys. which of these numbers of surveys
being returned would prevent nonresponse bias?
o a. 190
ob. 9
o c. 950
o d. 95

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
