Answer:
The density would be 2.89 g/ml
Step-by-step explanation:
To find this, we first need to find the mass of the rock. we can do this by subtracting the weight of the water and cylinder from the weight after the rock is added.
250g - 120g = 130g
Now we need to find the volume. To get this, we subtract the volume of the water before and after the rock is added.
75ml - 30ml - 45ml
Now we use the density formula and solve
D = m/v
D = 130g/45ml
D = 2.89 g/ml

The main difference can be directly observed in the
formulas used to calculate for the margin of error.
For the population mean, the margin of error would simply
be:
<span>MOE = z * s / sqrt(n)
where z is the z-score, s is the standard deviation and n is the number of
samples</span>
For the population proportion, the margin of error is:
MOE = z * sqrt[p (1 – p) / n]
<span>where p is the probability of success </span>
