Total Number of Peas (n) = 444 +163 = 607
Sample proportion of yellow peas (p) = 163/607 = 0.268
And q = 1-p = 1-0.268 = 0.732
Here the sample size (607) is greater than 30, using Central limit
theorem we can expect it approximately follows normal
distribution.
For 95% confidence interval, z = 1.96
95% confidence interval estimate of the percentage of yellow
peas
= p ± z * √( p * q /n )
= 0.268 ± 1.96 * √( 0.268 * 0.732 / 607)
= 0.268 ± 1.96 * 0.01797
= 0.268 ± 0.035
= ( 0.268 - 0.035 , 0.268 + 0.035)
= (0.233 , 0.303)
B)
No, confidence interval includes 0.25 , so the true percentage could easily equal to 25%
