Answer:

H0 : μ1 = μ2

H0 : μ1 < μ2

Step-by-step explanation:

Given :

Early studiers, group 1, mean μ1

Late studiers, group 2 ; mean, μ2

To test the claim that students who study earlier have an average score that is less than the average score for students

The null hypothesis ; there is no difference in average score

H0 : μ1 = μ2

Alternative hypothesis is early studiers means is less than average score of late studiers

H0 : μ1 < μ2

Let {an} be a sequence that satisfies the recurrence relation an = an-1 + 3 for n = 1, 2, 3, ... , and suppose that a0 = 2. What

Arturiano [62]

Given:

$a_n=a_{n-1}+3$

$a_0=2$

To find:

The values $a_1,a_2,a_3$ .

Solution:

We have,

$a_n=a_{n-1}+3$

For $n=1$ ,

$a_1=a_{1-1}+3$

$a_1=a_{0}+3$

$a_1=2+3$

$a_1=5$

For $n=2$ ,

$a_2=a_{2-1}+3$

$a_2=a_{1}+3$

$a_2=5+3$

$a_2=8$

For $n=3$ ,

$a_3=a_{3-1}+3$

$a_3=a_{2}+3$

$a_3=8+3$

$a_3=11$

Therefore, $a_1=5,a_2=8,a_3=11$ .
