Drawing a cartoon in pencil, then going back over it later with an ink pen is most similar to which biological process?
Montano1993 [528]

Given that the main reason for which an artist will retrace a drawing in pen is to <u>correct errors </u>and achieve a <u>final draft</u>, we can compare this to the biological process of DNA proofreading.

DNA proofreading is a <u>biological process </u>that takes place during the biosynthesis of DNA. During this time, a chain of <u>DNA </u>is read and a complementary chain is creating, <u>effectively duplicating the genetic code</u>.

During this process, DNA proofreading takes place. This is described as a process in which the DNA polymerase retraces the genetic code, detecting and fixing any errors in the synthesis before the strand is closed once again.

The fact is that both processes, despite taking place in astronomically different situations, share a final goal which is to prepare the "product" for the "final draft". This allows us to draw <u>valid</u> <u>comparisons </u>between the retracing of a <u>cartoon </u>and the <u>proofreading </u>of <u>DNA </u>by the DNA polymerase enzyme.

The mean resting pulse rate for men is 72 beats per minute. a simple random sample of men who regularly work out at mitch's gym
tamaranim1 [39]

Claim: the mean resting pulse rate for men is less than 72 bpm.

Symbolic form would be: μ < 72

Step 1: null hypothesis  : μ > =  7 2 b p m

Step 2: alternative hypothesis:  μ <  7 2 b p m



Step 3: the test statistic is z = mean – μ / standard dev/sqrt (n) = -3/4 / 1.7639 = -1.92


Step 4: c v method: since z α = -1.645, the test static is z = -1.92 is less than the CV, we reject null hypothesis


            P Value method: area is 0.0274, since the p value is <= α, reject null hypothesis.

Step 5: the sample data support the claim that the mean resting pulse rate for men is less than 72 bpm.
