A game of chance has a spinner with five equal-sized sections, The results of 625 spins are shown below. For which color is the
andrew-mc [135]

The color that has the greatest difference between the theoretical and experimental probability is yellow.

<h3>Which color has the greatest difference?
</h3>

Theoretical probability of each color = number of color in each section / total number of sections

1/5 = 0.2

Experimental probability is based on the result of an experiment that has been carried out multiples times

Experimental probability

Experimental probability of choosing orange = 118 / 625 = 0.19

Difference = 0.2 - 0.19 = 0.01

Experimental probability of choosing purple = 137 / 625 = 0.22

Difference 0.22 - 0.2 = 0.02

Experimental probability of choosing brown = 122 / 625 = 0.20

0.2 - 0.2 = 0

Experimental probability of choosing yellow = 106 / 625 = 0.17

0.20 - 0.1696 = 0.0304

Experimental probability of choosing green = 142 / 625 = 0.23

0.2272 - 0.20 = 0.0272

Researchers are investigating whether people who exercise with a training partner have a greater increase, on average, in target
bulgar [2K]

Answer:

1 - If method I is used, population of generalization will include all those people who may have varying exercising habits or routines.  They may or may not have a regular excersing habit.  In his case sample is taken from a more diverse population

2 - Population of generalization will include people who will have similar excersing routines and habits if method II is used since sample is choosen from a specific population

Step-by-step explanation:

Past excercising habits may affect the change in intensity to a targeted excersise in different manner. So in method I a greater diversity is included and result of excersing with or without a trainer will account for greater number of variables than method II.

Rolling a 3 or rolling an odd number on a six sided die. Is it mutually exclusive or non-mutually exclusive? Give one reason.
Cerrena [4.2K]

Answer:

Non-mutually exclusive

Step-by-step explanation:

both events can happen simultaneously... 3 is an odd number, events A and B  have a common outcome.

It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.
