A 95% lower confidence bound (LCB) for the difference between population proportions can be constructed using the following equation:
LCB = 
Lower Confidence Bound
The lower limit of a confidence interval, indicating the smallest value that, based on the data, might be considered a plausible estimate of a parameter.
Population Proportions
A statistical measure that represents the fraction or percentage of units in a population that possess a certain trait or characteristic.

Final Answer :
True
Explanation :
The formula for constructing a 95% LCB for the difference between population proportions is:
LCB = (p1 - p2) - 1.96√[(p1(1-p1)/n1) + (p2(1-p2)/n2)]
where p1 and p2 are sample proportions and n1 and n2 are sample sizes. The formula given in the question is incorrect.
LCB = (p1 - p2) - 1.96√[(p1(1-p1)/n1) + (p2(1-p2)/n2)]
where p1 and p2 are sample proportions and n1 and n2 are sample sizes. The formula given in the question is incorrect.
