X = number of bags needed
The equation that will be set up is
10,000/20 = 140,000/x
cross multiplying gives
10,000x = 20*140,000
10,000x = 2,800,000<span>
now divide both sides by 10,000 to fully isolate x
</span>10,000x = <span>2,800,000
</span>10,000x<span>/10,000</span> = 2,800,000/10,000
x = 280
So you'll need 280 bags
Answer:
Step-by-step explanation:
Answer:
E. There is sufficient evidence that the mean of the pressure required to open a certain valve has increased.
Step-by-step explanation:
Null hypothesis(H0): μ= 8.4 psi
Alternative hypothesis (H1): μ> 8.4 psi
If the test was due with a representative minimum number of observations. And, if the null hypothesis was rejected, then the mean pressure required to open a valve is greater than 8.4 psi. We can conclude that (at a certain level of confidence) there is sufficient evidence that the mean of the pressure required to open a certain valve has increased.
