The continental crust is

Ludmilka [50]

The continental crust is up to 70 km thick.

Explanation:

Upto 40% of the earth is made up of continental crust. Sedimentary, igneous and metamorphic ricks make up the continental crust. It makes up the upper layer of continents and shallow seabed areas near the shores.

Continental crust is thicker than oceanic crust with a thickness ranging from 25 km to 70km continental crust makes up 70% of earth’s volume and is usually located above sea level with a few exceptions like the Zealand continental crust region which is largely under water.

Answer:

The t-test

Explanation:

The researcher should use a t-test to compare the two means and check if they are significantly different from each other.

In using the t-test, both null (H0) and alternate (H1) hypothesis are made such that:

H0: n1 = n2
H1: n1≠ n2

Thereafter, the value of t is calculated and compared to its critical value on the table. The formula for calculating the t goes thus:

$t = \frac{Y_1 - Y_2}{\sqrt{\frac{S_1}{n_1} + \frac{S_2}{n_2} } }$

where, Y1 = mean of population 1, Y2 = mean of population 2, S1 = variance of population 1, S2 = variance of population 2, n1 = number of individuals in population 1 and s2 = number of individuals in population 2.

At the end of the day, if the calculated t value is more than the critical value of t, the H0 is rejected and it shows that the two means are significantly different. Otherwise, the H0 is accepted and this shows that there is not significant difference between the mean of population 1 and that of 2.
