Agenetic experiment with peas resulted in one sample of offspring that consisted of 447447 green peas and 172172 yellow peas. a. construct a 9090% confidence interval to estimate of the percentage of yellow peas. b. it was expected that 25% of the offspring peas would be yellow. given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations?

The results do not contradict expectations.

Step-by-step explanation:

Given that a genetic experiment with peas resulted in one sample of offspring that consisted of 447 green peas and 172 yellow peas.

Proportion of yellow peas =

Std error = 0.25(0.75)/sq rt 619

=0.0174

Proportion difference = 0.2779-0.25=0.0279

Test statistic = 0.0279/0.0174 =1.603

p value = 0.1089

For two tailed we have p value >0.10

Hence accept null hypothesis.

The results do not contradict expectations.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
