ke. Complete parts (a) through (c) belaw. a. If 1 male colege student in randoenly selected, find
the probabeby that he gains betweon 0kg and 3kg aining freshman yeae. The probability is
(Round to four decimal places as needed) b. If 16 male. college students are randembly selecied,
find the probability that their mean woight gah during freshman year is between 0kg and 3kg The
probability is (Round to four decinal placas as needec.) c. Why can the nomal dintribution be uoed
in pan (b), even though the sample size doen not axcaed 30 ? A. Since the distribution is of
individuala not sarpile means, the distribution is a noemal dstribidon for any sample slze 8. Since
the weight gain excesds 30 , the diatribution of 6ample meane is a normal dsa plifor for ary sample
slee C. Shce the disulbutan is of sample meanns not individuah: the distribution is a nornal cla
bibution for any sample slae 0. Since the oiginal popu fatlon has a normal eistribution, thi
distrbution of sample means s a nongal distribution lor any sample size.
KITCHEN LAB RATE OF CATALASE You are now ready to comple.pdf
1. KITCHEN LAB - - RATE OF CATALASE
You are now ready to complete the experiment for this Activity. Plan, perform and analyze results
from a lab using household materials to investigate the effect of a factor on enzyme activity. Your
teacher will tell you which factor you will investigate. As you prepare for, perform and report about
your investigation, look for opportunities to practice good Organization Skills. Take this opportunity
to act on some of the feedback from the lab investigations you've already done. Also, look for
ways that you can plan your investigation to control as many variables as you can.
Your report will:
EXPERIMENT: RATE OF CATALASE
Materials Needed:
Procedure:
You get to plan your own procedure for this investigation. Your procedure must allow you to collect
at least 5 different results, including a control group. You may find it useful to to add the substrate
last of all the ingredients added to the reaction.
Throughout this investigation you will estimate the rate of the reaction (how rapidly the solution
bubbles) on a scale of 0-5 (o=no reaction, 1=slow, .... 5= very fast). Assume that the normal
reaction rate of catalase is a 3.
