In each case, determine whether the sample sizes are large enough to conclude that the sampling distribution

Question:

In each case, determine whether the sample sizes are large enough to conclude that the sampling of (p̂1 - p̂2) is approximately normal.
a. n1 = 12, n2 = 14, p̂1, = .42, p̂2 - .57
b. n1 = 12, n2 = 14, p̂1, = .92, p̂2 = .86
c. n1 - n2 = 30, p̂1 = .70, p̂2 = .73
d. n1 = 100, n2 = 250, p̂1 = .93, p̂2 = .97
e. n1 = 125, n2 = 200, p̂1 = .08, p̂2 = .12 Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
