a) Z Test(n>30)

b) t=2.028

Step-by-step explanation:

Average A=3400

Mean $\=x=3200$

Sample size n=36

Standard deviation $\sigma=600mg$

Generally using the Z Test(n>30)

Generally the equation for Standard Error S.E is mathematically given by

$S.E=\frac{600}{\sqrt{36}}$ }

S.E=100

Generally the equation for Z test is mathematically given by

$Z=\frac{\=x-A}{\sigma\sqrt{n}}$

$Z=\frac{3200-3400}{600\sqrt{36}}$

Z=-2

From table

T critical= (Z,df)

Where

df=n-1

df=35

Therefore

t=2.028
