Answer: The value of test statistic is 2.442.
Step-by-step explanation:
Since we have given that
n = 238
Sample mean = 23.2 minutes
Standard deviation = 20.26 minutes
Hypothesis :

So, the test statistic value would be

Hence, the value of test statistic is 2.442.
I=prt.....
i=5000*10*0.03=1500
5000+1500=6500
It is not reasonable because 53.85 x 5 is 269.25 which isnt close to 350
Answer:

Step-by-step explanation:
It is given that the pressure, P, of the given mass of a gas in a closed cylinder varies inversely as the volume, V, of the cylinder.
Therefore, P ∞
So,
where k is the constant of proportionality.
Hence, the equation that models the given statement is :
or
PV = k
