a)
The z value at 90% confidence interval is,
alpha = 1 - 0.90 = 0.1
alpha/2 = 0.1/2 = 0.05
Zalpha/2 = Z0.05 = 1.64
Total peas = 439+ 157 = 596
proportion for yellow peas = 157/596 = 0.263
CI = p +/- z *sqrt(p*(1-p)/n)
= 0.263 +/- 1.64 *sqrt(0.263*(1-0.263) / 596)
= (0.234 , 0.293)
0.234 < p< 0.293
b)
No, the confidence interval includes 0.25, so the true percentage could easily equal 25%
