The standard germination rate for foxglove seeds (Digitalis) produced by a large nursery is a 70% germination rate. Twelve samples of seeds have been stored for 1 year. When planted it is determined that their germination rate is 62% with a SEM of 8%.

What type of t-test should you use?

What is the t-value?

Would you use a one-tailed test, or a two-tailed test?

What are the degrees of freedom?

Using the table of t-values given at the end of this assignment, would you conclude that this difference was likely to have happened by change? Explain your reasoning.

Information on a large packet of seeds indicates that the germination rate is p0=92%. Some researchers claim that the proportion of germination should be higher than that. (a) (2 points) Based on the indication of the information, what’s the probability that more than 95% of the 300 seeds in the packet will germinate? (b) (3 points) Now a random sample containing 300 seeds with 290 germinated is chosen to test this claim. Based on the sample, construct a 90% conﬁdence...
