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:
republicans
Step-by-step explanation:
Given, there are 60% democrats and republicans 40%
60% of the democrats voted for democrats and 95% of the republican voted for their candidate
therefore
% of votes that went for Democrats =0.6*0.6=0.36
= 36%
% of votes that went for Republics=0.4*0.95=0.38
= 38%
Since the republicans have more % of votes thus Republic's mayor runs city hall.
The unit price is $6.25 because $43.75 divided by 7 is $6.25
