A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 317 people over the age of 55. 70 dream in black and white, and among 296 people under the age of 25. 12 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under
a. Test the claim using a hypothesis test.
b. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test?
A. H0:P1=P2
H1:P1 B. H0:P1=P2
H1:p1>p2
C. H0:P1=P2
H1:P1≠P2
D. H0:p1≤p2
H1:P1≠p2
E. H0:p1≥p2
H1:p1≠p2
F. H0:P1≠P2
H1:P1=P2
Identify the test statistic. z=

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)
