VERY URGENT PLEASE HELP!!

Question 1 [4 points]: A botanist is interested in comparing the growth response of dwarf pea stems against two different levels of the hormone indoleacetic acid (IAA). Using 16- day-old pea plants, the botanist obtains 5-millimeter sections and floats these sections on solutions with different hormone concentrations to observe the effect of the hormone on the growth of the pea stem. Let z and #2 denote, respectively, the mean growths that can be attributed to the hormone during the first 26 hours after sectioning for (0.5) (10)- and 10-4 levels of concentration of IAA. (a) The botanist claims that the mean growth will be smaller after sectioning for 10-4 levels of concentration of IAA. Formulate hypotheses to verify this claim. (b) The botanist measured the growths of pea stem segments, in millimeters, for m = 11 observations after sectioning for (0.5)(10)-* levels of concentration of IAA. She did the same with n2 = 13 observations after sectioning for (10) levels of concentration of IAA. Here are some descriptive statistics. > sd (growth1) [1] 0. 3704979 > sd (growth2) [1] 0. 4431311 > summary (growth1) Min. ist Qu. Median Mean 3rd Qu.

(c) Obtain the p-value to test the hypotheses from part (a). (d) Based on the p-value from part (c), what should the botanist conclude at a level of significance of a = 5%
