Answer:

The right answer is "1.818".

Step-by-step explanation:

The given values are:

a = 0.1

\bar{x} = 94

\mu = 90

Now,

The test statistic will be:

⇒  t=\frac{\bar{x}-\mu}{\frac{s}{vn} }

On substituting the given values, we get

⇒     =\frac{94-90}{\frac{22}{10} }

⇒     =\frac{4}{2.2}

⇒     =1.818
