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 germinatin 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%. a) State Ho. H1 and a b) Using the value of p in Ho, are both np > 5 and nq > 5? Can we use the normal distribution for p? Explain c) Calculate the sample test statistic p.
