Pesticides utilized in food creation can be found in food devoured by people. An examination zeroing in on chickens presented to malaoxon was led. The chickens were likewise presented to a liver chemical inducer to decide if liver detoxification of the pesticide is influenced. The accompanying information were accounted for as a level of typical pesticide detoxification (y) and level of ordinary liver protein levels (x):

Chemical level cr) Detoxification level (v) 95 108 110 126 118 102 124 121 145 118 140 155 185 158 19C. 178 205 159 222 184

Question 14

Carbon dioxide is known to critically affect microbiological development. Limited quantities of CO2 invigorate the development of numerous living beings, while high focuses repress the development of most. The last impact is utilized monetarily when transient food items are put away. An examination is directed to explore the impact of CO2 on the development pace of Pseudomonas fragi, a food spoiler. Carbon dioxide is managed at five diverse air pressures. The reaction noted is the rate change in cell mass following a 1-hour developing time. Ten societies are utilized at each level. The accompanying information are discovered: Factor level (CO2 pressure in environments)

0.0 .083 .29 .50 .86 62.6 50.9 45.5 29.5 24.9 59.6 44.3 41.1 22.8 17.2 64.5 47.5 29.8 19.2 7.8 59.3 49.5 38.3 20.6 103 58.6 48.5 402 29.2 17.8 64.6 50.4 38.5 24.1 22.1 50.9 35.2 30.2 22.6 56.2 49.9 27.0 32.7 16.8 52.3 42.6 40.0 24.4 15.9 62.8 41.6 33.9 29.6 8.8

Direct a relapse study, and compose a report that sums up the consequences, everything being equal, and graphical apparatuses that you utilized in the examination.

Question 15

An electrical designer is worried about foreseeing power request dependent on temperature of the flow day. This would empower the organization to purchase and move power dependent on transient climate expectations, and, thus, brownouts could be decreased or kept away from. An interest scale was contrived from zero to ten, with zero addressing extremely low interest and ten addressing greatest interest. An irregular example of 40 days over the 365-day year was gotten, yielding the accompanying information:

Ohs. no. Temperature Request Obs. no. Temperature Request 1 30 2.9 21 67 ..4 2 11 5.1 22 33 3.1 3 97 4.0 23 81 1.9 4 41 2.0 24 101 3.5 5 53 1.6 25 84 1.5 6 105 4.5 26 36 1.2 7 68 .3 27 98 3.1 8 1 8.0 28 79 1.0 9 48 .6 29 98 3.6 10 106 5.6 30 3 7.8 11 98 3.3 31 86 2.7 12 33 2.6 32 34 2.2 13 10 5.2 33 108 4.5 14 63 .9 34 14 4.9 15 50 1.3 35 89 2.9 16 2 7.1 36 53 1.3 17 45 1.4 37 55 .7 18 59 .6 38 15 4.7 19 7 6.3 39 87 2.2 20 96 3.5 40 87 1.9

(a) Plot the information for the free factor (temperature) versus the reaction variable (request). Do you accept that a straightforward direct relapse line will anticipate request well for this case? Why?

(b) Make two separate plots utilizing just temperature esteems equivalent to or under 60 degrees for one chart and a different diagram for temperature esteems more prominent than 60 degrees. Do you feel that utilizing two separate relapse lines to foresee request could function admirably?

(c) Would you be able to think about another approach to show these information for foreseeing request? Talk about potential other options.

Question 16

The basic direct relapse model is a polynomial model of what degree? Confirm that, for this situation, the ordinary conditions surrendered (12.3) lessen to those given in Chap. 11 for the basic direct relapse model.
