Answer:
The test statistic is
.
Step-by-step explanation:
The test statistic for hypothesis test for the significant difference between two proportions is:
![z=\frac{\hat p_{1}-\hat p_{2}}{\sqrt{P(1-P)[\frac{1}{n_{1}}+\frac{1}{n_{2}}]}}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B%5Chat%20p_%7B1%7D-%5Chat%20p_%7B2%7D%7D%7B%5Csqrt%7BP%281-P%29%5B%5Cfrac%7B1%7D%7Bn_%7B1%7D%7D%2B%5Cfrac%7B1%7D%7Bn_%7B2%7D%7D%5D%7D%7D)
The combined proportions P is computed using the formula:

Here,
Sample 1 represents the proportion over the sample of people using the nicotine gum.
Sample 2 represents the proportion over the sample of people using the placebo.
*Answer:*
False
