The formula to find the volume multiplies the length by the width by the height.A cube has all edges the same length .If we multiply the edges three times we get the volume of any cube.
Volume of cube with sides a is Volume V=
In the question the cube is having an edge of 3.4 meters
Volume V=
Volume of cube is 39.3 cubic meters.
Complete Question:
a) Is it plausible that X is normally distributed?
b) For a random sample of 50 such pairs, what is the (approximate) probability that the sample mean courtship time is between 100 min and 125 min?
Answer:
a) It is plausible that X is normally distributed
b) probability that the sample mean courtship time is between 100 min and 125 min is 0.5269
Step-by-step explanation:
a)X denotes the courtship time for the scorpion flies which indicates that is a real - valued random variable, and since normal distribution is a continuous probability distribution for a real valued random variable, it is plausible that X is normally distributed.
b) Probability that the sample mean courtship time is between 100 min and 125 min
From the probability distribution table:
