UQuestion 15Scenario 3-1How many many blooms are on the peony plants at Bouquet Farms? In previous years, you knowthat each plant on average would produce 30 blooms. You are interested if your yield this year issmaller because the past few months have been cold and wet. Suppose a random sample of 100plants yielded the following data on the number of blooms per plant: X-25, S-8. You areinterested in determining whether there is evidence that the mean number of blooms is less than30.Referring to Scenario 3-1, state the correct decision rule for a 0.05.Reject HO if Tstat > 1.6604O Reject HO if Tstat < -1.96Reject HO if Tstat < 1.6604O Reject HO if Tstat < -1.6604.

A company was concerned about the length of time a particular vitamin they produce retained its potency. Potency was measured for a random sample of 10 bottles that had just been produced and also for a random sample of 10 bottles after 1 year in storage. The resulting data was used to calculate the summary statistics below. Standard n Mean Deviation Newly produced 10 10.37 0.32 Stored for 1 year 10 9.83 0.24 Difference (New - Stored) 10 0.54 0.43

Is the following results section correct? A single sample t test was conducted to measure the affect of a drug on short-term memory in 8 randomly selected participants. Each participant was given the drug, and then told to memorize a list of 10 words. After 15 minutes, they were tested for retention. The result was statistically significant, t (7) = 4.32, p = .003, two-tailed., 95% CI [6.9054, 9.0946].
