The test statistic will be "-2.33". A further explanation is provided below.

Step-by-step explanation:

According to the question,

$H_0: \mu = 2.05$

$H_0: \mu < 2.05$

Given:

$\bar x = 1.98$

s = 0.3

n = 100

The test statistics will be:

⇒ $t_0 = \frac{\bar x - \mu_0}{\frac{s}{\sqrt{n} } }$

$=\frac{1.98-2.05}{\frac{0.3}{\sqrt{100} } }$

=-2.33

and the P-value will be:

= $0.011< \alpha$
