Well you add them all up then divide by five, because thats how many days it was recorded, and the average is -1.2
Volume of a sphere = (4/3) pi r^3
required volume = (4/3) pi (6^3-5^3)
= (364/3) * pi cu ins.
Answer:
a) 13.277
Step-by-step explanation:
The chi-square critical value can be assessed using chi-square area table and for this table need value of alpha and degree of freedom.
The value of alpha is given which is 0.01 and degree of freedom can be calculated as
df=k-1
Where k represent the categories which are 5 in the given case.
df=5-1=4.
For alpha=0.01 and df=4, we get the chi-square critical value 13.277.
