A botanist has produced a new variety of hybrid wheat that is better able to withstand drought than other varieties. The botanist knows that for the parent plants, the proportion of seeds germinating is 80%. The proportion of seeds germinating for the hybrid variety is unknown, but the botanist claims that it is 80%. To test this claim, 400 seeds from the hybrid plant are tested, and it is found that 312 germinate. Use a 5% level of significance to test the claim that the proportion germinating for the hybrid is 80%.
Identify the null and alternative hypotheses to this problem.
Ho: p = 0.8 vs. Ha: p ≠ 0.8*
Ho: p > 0.8 vs. Ha: p < 0.8
Ho: p < 0.8 vs. Ha: p ≥ 0.8
Ho: p > 0.8 vs. Ha: p ≤ 0.8
Ho: p ≤ 0.8 vs. Ha: p ≥ 0.8
the null and alternative hypotheses to this problem. is as :
Ho: p = 0.8 vs. Ha: p ≠ 0.8*

A botanist has developed a new hybrid cotton plant that can withstand insects better than other cotton plants. However, there is some concern about the germination of seeds from the new plant. To estimate the probability that a seed from the new plant will germinate, a random sample of 3000 seeds was planted in warm, moist soil. Of these seeds, 2030 germinated. (a) Use relative frequencies to estimate the probability that a seed will germinate. What is your estimate? (Enter...
