Answer:
We accept H₀. We do not have argument to keep the claim that the mean breaking strength has increased
Step-by-step explanation:
Normal Distribution
Population Mean μ₀ = 1850 pounds
Standard Deviation σ = 90 pounds
Type of test
Null Hypothesis H₀ ⇒ μ = μ₀
Alternative Hypothesis Hₐ ⇒ μ > μ₀
A one tail test (right)
n = 21 as n < 30 we use t-student table
degree of fredom 20
t = 2.845
Sample mean μ = 1893
Then, we compute t statistics
t(s) = [ 1893 - 1850 ] / 90/ √n
t(s) = 43 * 4,583 / 90
t(s) = 197,069 / 90
t(s) = 2,190
And we compare t and t(s)
t(s) = 2.190
t = 2.845
Then t(s) < t
We are in the acceptance zone, we accept H₀
Answer:
she needs to earn at least $200 more to equal $2,700, so
200=x($amount of needed sales) * .06
200/.06=x
$3,333=x is sales needed to meet goal
variable is $ amount of sales needed to earn $2,700 this month.
Commission rate as decimal=.06
Inequality that represents is...
x> or = $3,333
Hey there! :)
Answer:
y = 0, also known as the x-axis.
Step-by-step explanation:
The equation 
is an exponential function.
There is an asymptote at y = 0, or the x-axis because:
An exponential function, unless containing a vertical shift, can never cross the x-axis resulting in an asymptote at y = 0.
