Answer 1

Solution :

$\mu$ = 4

$\bar x$ = 4.8

s = 2.3

n = 15

This is the two tailed test .

Test statistic = t

= ($\bar x$ - $\mu$ ) / s / $\sqrt$ n

= (4.8 - 4) / 2.3/ 15 $\sqrt$

= 1.347

P-value = 0.1993

$\alpha$ =0.05

p = 0.1993 ≥ 0.05, it is concluded that the null hypothesis is not rejected.
