While conducting experiments, a marine biologist selects water depths from a uniformly distributed collection that vary between
mr_godi [17]

Answer: The expected value of the water depth is 4.5 m.

Step-by-step explanation:

Let x be a random variable which is uniformly distributed in interval [a,b] .

Then the mean of the distribution is ghiven by :-

E(x)=\dfrac{a+b}{2}

Given : While conducting experiments, a marine biologist selects water depths from a uniformly distributed collection that vary between 2.00 m and 7.00 m.

Then, the expected value of the water depth = \dfrac{2+7}{2}=\dfrac{9}{2}=4.5

Hence, the expected value of the water depth is 4.5 m.

Can you help me to create a histogram graph with the following data please?
AlekseyPX

The attached graph represents a histogram that has a range of 55

<h3>How to create the histogram?</h3>

The range is given as:

Range = 55

The range is calculated as:

Range = Maximum - Minimum

So, we have:

Maximum - Minimum = 55

Rewrite as:

Maximum = Minimum + 55

Let the minimum be 10.

So, we have:

Maximum = 10 + 55

Evaluate

Maximum = 65

The following dataset can be used to create the histogram

Score   Frequency

10           2

15            5

45          3

65         1

This is so because it has a range of 55

See attachment for the histogram
