QUESTION 17 A genetic theory says that a crass between two pink flowering plants will produce red flowering plants 25% of the time. To test the theory, 100 crosses are made and 34 of them produce a red flowering plant. Is this strong evidence that the theory is wrong? Carry out the appropriate hypothesis test at the 5% significance level A. The hypothesis for this test is: --(enter one of the letter options: a, b, c or d) a. Ho: = .25 vs Ha: # .25 b, Ho: p-25 vs HA: p # .25 c. Ho: p = .25 vs HA: p :25 B. The test statistic is -(enter a, b, c, d or e) (e) 2.08 (a) 0.16 (b) 1.39 C. And the p-value is (c) 1.62 (d) 1.85 (enter a, b, c, d, e, f.g orh) (a) 0.019 (b) 0.038 (c) 0.053 (d) 0.065 (e) 0.083 (0 0.106 (g) 0.166 (h) 0.26 D. There- is / is not) enough statistical evidence to conclude that the

Explanation / Answer

A. Correct answer: Option (B)
B. Sample proportion p = 34/100 = 0.34
Test statistic
Z = (p - P) / SQRT(PQ/n) = (0.34-0.25)/ Sqrt(0.25*0.75 / 100) = 2.0785

Correct Answre: Option (E) 2.08

C. P-value is - Option (B) 0.038

D. There is enough statistical evidence to conclude that the theory is wrong

since P-vallue < alpha 0.05
