Kimmy Schmidt has 34 plants! Left untreated, their mature heights are normally distributed

One side hypothesis test

1. Kimmy Schmidt has 34 plants! Left untreated, their mature heights are normally distributed with an average height of 14.8cm, and a sd of 4.3cm! Kimmy has applied a treatment to them, which should increase their height! (In this sense, Kimmy is emulating a kind of agricultural study made famous by the founder of modern statistics, R.A. Fisher!) Their average mature height turns out to be 15.9cm! Kimmy needs to know if this difference is statistically significant at the .05 level! Help her find it! Show your work!

2. Suppose your t-statistic has a value of 2.3, where n = 4. Estimate the p-value using the table above, for a 1-sided test where H1 holds that μ is less than what H0 holds
