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:
Step-by-step explanation:
<u>Informação recuperada:</u>
(UFRGS) Se 10x = 20y , atribuindo 0,3 para log 2 , então o valor de x/y é
1) Primeiro, passando o 10 para o 2º membro como base do logaritmo:
2) Aplicando a propriedade do produto de logaritmo:
3) Como quero o quociente divido ambos os lados por y
(6, 2 )
substitute x = 5 into the equation and solve for y
6y + 8 = 20 ( subtract 8 from both sides )
6y = 12 ( divide both sides by 6 )
y = 
= 2
the ordered pair is (5, 2 )
