no
Explanation:
H0: mean of sample=105
Ha: mean of sampe≠ 105
t-statistic= (population mean-sample mean)/(standard deviation/√sample size)
t-statistic= (105-103.3)/(16.3/√33)
t-statistic= 0.5991
degress of freedom= 32

Income Elasticity of Demand(IED)= Percentage change in quantity demanded/ Percentage change in income
-Percentage change in Q:
%Change in quantity demanded= (q2-q1/q1) = (10-8)/8= 0.25
-Percentage change in Income:
%Change in income= (i2-i1/i1) = (4,500-4,000)/4,000= 0.125
IED= 0.25/0.125= 2
