Question 1057902
The proportion of interest is 53/1852=0.0286
The new proportion is 1751/4699=0.3726
Ho=no difference
Ha=difference
alpha=0.01
1 sample proportion looking at 0.0286
use a z(0.995)2-tailed with critical value |z|>2.576
z=(0.3726-0.0286)/sqrt {(.0286)(0.9714)/4699}; std error=0.00243
z=(0.3440)/0.00243=141.56
Strongly reject Ho and high likelihood that there is a higher percentage of customers who were against them.
