The Wind Mountain excavation site in New Mexico is an important archaeological location of the ancient Native American Anasazi culture. The following data represent depths (in cm) below surface grade at which significant artifacts were discovered at this site (Reference: A.I. Woosley and A.J.

legal case rested on whether a patent witness' signature was written on top of key text in a notebook or under the key text. The zinc measurements for three notebook ocations on a text line, on a witness line, and on the intersection of the witness and text line are provided in the table below. Complete parts a through c below. ext line Witness line 0.319 0.384 0.327 ntersection A. Ho: Hw-H₁0, Ha: Hw-₁0 OB. Ho: Hw-H₁0, Ha: Hw-₁ OC. Ho: HT-Hw=0, H₂: HT-H₁ <0 a O D. Ho: HT-HW = 0, H₂: HT-H₁0 Find the test statistic. 0.321 0.307 0.327 . Use a test (at a = 0.02) to compare the mean zinc measurement for the witness line with the mean for the intersection. Select the correct hypotheses below. t=(Round to two decimal places as needed.) Find the p-value. p-value = (Round to three decimal places as needed.) Choose the correct conclusion below. Assume α = 0.02. 0.409 0.449 0.305 0.408 0.298 MacBook Pro 0.269 0.337 O A. Do not reject Ho. There is sufficient evidence that the mean measurements B.…

by using r -studio pls do parts a-c
