Listed below are the lead concentrations in g/g measured in different traditional medicines. Use a 0.05 significance level to test the claim that the mean lead concentration for all such medicines is less than 14 g/g. 12 10 6.5 12 4 12.5 5.5 9 17.5 18

Explanation / Answer

Answer - 1: The statistical software output for this problem is:

One sample T hypothesis test:
: Mean of variable
H0 : = 14
HA : < 14

Hypothesis test results:

Hence,

A) Test statistic = -2.219

B) P - value = 0.027

Answer - 2: The statistical software output for this problem is:

One sample T hypothesis test:
: Mean of variable
H0 : = 60
HA : 60

Hypothesis test results:

Hence,

A) Test statistic = 2.609

B) P - value = 0.021

Variable Sample Mean Std. Err. DF T-Stat P-value Data 10.7 1.4873541 9 -2.218705 0.0268
