Answer:
a
The estimate is
b
Method B this is because the faulty breaks are less
Step-by-step explanation:
The number of microchips broken in method A is
The number of faulty breaks of method A is
The number of microchips broken in method B is
The number of faulty breaks of method A is
The proportion of the faulty breaks to the total breaks in method A is
The proportion of the faulty to the total breaks in method B is
For this estimation the standard error is
substituting values
The z-values of confidence coefficient of 0.95 from the z-table is
The difference between proportions of improperly broken microchips for the two breaking methods is mathematically represented as
substituting values
The interval of the difference between proportions of improperly broken microchips for the two breaking methods is
