Answer:

The Calculated "t' value is# 24.5#
Table value (t Value) for 5% level of significance and 149 degrees of freedom is #1.645#

Explanation:

You didn't give the significance level.
Let me use 5% significance level.

Since the sample mean is greater than population mean, we can go for Right Tail test.

Table value (t Value) for 5% level of significance and 149 degrees of freedom is 1.645

Calculate Standard Error

#SE =s/sqrt(n)=4/sqrt(150)=4/12.25=0.3265#

Calculate t value for the given values.

#t=(barx-mu)/(SE)=(16-8)/(0.3265)=8/(0.3265)=24.5#

The Calculated "t' value is# 24.5#
