Use R. Here is the ORCHAD data set:

Insecticides used in orchards Read the orchard data & into R's workspace. (From MS 8.44) Insecticides used in orchards. Environmental Science & Technology (Oct. 1993) reported on a study of insecticides used on dormant orchards in the San Joaquin Valley, California. Ambient air samples were collected and analyzed daily at an orchard site during the most intensive period of spraying. The thion and oxon levels (in ng/m3) in the air samples are recorded in the table, as well as the oxon/thion ratios. A researcher wanted to compare the mean oxon/thion ratios of foggy and clear/cloudy conditions at the orchard using a test of hypothesis. Use alpha = 0.05 Suppose: Ho : Heloudyclear - Mfog = 0 H1 : Adoudyclear - Mfog # 0 the code suggested was the following: df % mutate(NEWCON = ifelse (CONDITION == "CLEAR" | CONDITION == "CLOUD", "CCLOUD", "FOG" )) When using the t-test function the following was proposed for the options of the t-test: Are the t-test options correct? > t. test (RATIO - NEWCON, mu = @, var .equal = TRUE, data = of) Two Sample t-test data: RATIO by NEWCON t = 2.0467, of = 10, p-value = 0.06788 alternative hypothesis: true difference in means between group CCLOUD and group FOG is not equal to @ 95 percent confidence interval: -0. 01581919 0.37281919 sample estimates: mean in group CCLOUD mean in group FOG 0. 45225 0. 27375 Yes or No? Question 9 = the probability of a type 1 error and a type 1 error is the event of falsely rejecting the NULL hypothesis True or False? Question 10 Power = P(Reject a TRUE NULL hypothesis) True or False
