vagabundo [1.1K]

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:

H₀: The mean respiration rate of students is 32, i.e. μ = 32.

Hₐ: The mean respiration rate of students is less than 32, i.e. μ < 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.

Sierra is saving money to buy a bike the bike costs $245. she has $125 saved and each week she adds $15 to her savings. how many

beks73 [17]

You should start with an equation.
$245 = 125 + 15x$
The 'x' represents the week.

so now, we have to subtract 125 from the total amount which is 245.
$245 - 125 = 120$
now we have
$120 = 15x$
to find 'x', we must divide 15 on each side
$\frac{120}{15} = \frac{15x}{15}$
we are now left with
$8 = x$
that means Sierra will have 8 weeks until she has enough money to buy the bike
