To determine if loans from bank 1 are less affordable than loans from bank 2, the mean loan rate of the two competing banks is compared. Twenty-five loans are randomly sampled from each bank and the loan rates are recorded. Both populations have normal distributions with unknown standard deviations. State the null and alternative hypotheses.

Step-by-step explanation:

The null hypothesis is an smoothies l that states that there is no difference or association between populations while the alternative hypothesis always aims to prove otherwise.

In this case study, the null hypothesis is that loans from bank 1 are more affordable than loans from bank 2. Bank 1 average loan >= bank 2 average loan.

Alternative hypothesis: loans from bank 1 are less affordable than loans from bank 2

Bank 1 average loan < bank 2 average loan.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
