Answer:
There is not sufficient evidence to support the claim.
Step-by-step explanation:
The claim to be tested is:
The mean respiration rate (in breaths per minute) of students in a large statistics class is less than 32.
To test this claim the hypothesis can be defined as follows:
<em>H₀</em>: The mean respiration rate of students is 32, i.e. <em>μ</em> = 32.
<em>Hₐ</em>: The mean respiration rate of students is less than 32, i.e. <em>μ</em> < 32.
The sample mean respiration rate of students is 31.3.
According to the claim the sample mean is less than 32.
The sample mean value is not unusual if the claim is true, and the sample mean value is also not unusual if the claim is false.
Thus, there is not sufficient evidence to support the claim.

Answer:
34 games
Step-by-step explanation:
let the number of losses be
let the number of victories be
<u>the Phoenix murmur had 12 more victories than losses:</u>
<u>The number of victories they had was one more than two times the number of losses:</u>
<em>We have 2 expressions for , equating these 2, we can solve for :</em>
So 11 games, they lost.
Using this value, we can plug into the 1st equation to solve for v:
So 23 games, they won.
Given that no draws, they played a total of 23 + 11 = 34 games this season
