When determining sample size for a proportion, we need to know p. If we have no prior information regarding this value, how

The concentration level of Zinc in milligrams in two types of soil was found to be as follows Soil A:  2.1    4.0    6.3    5.4     4.8    3.7    6.1    3.3 Soil B:  0.6    3.1    2.5    4.0     6.2    1.6    2.2    1.9    5.4 To check the claim that the medians of concentration level in the two soils were unequal, we conducted an appropriate test at and we found that the test statistics is equal to   a.  57  b.  65 c.  47 d.  None   Decision   a.  we reject the claim  b.  we fail to reject the claim c.  we can’t decide d.  None

Help me answer questions in pictures with the following question: In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. Is fishing better from a boat or from the shore? Pyramid Lake is located on the Paiute Indian Reservation in Nevada. Presidents, movie stars, and people who just want to catch fish go to Pyramid Lake for really large cutthroat trout. Let row B represent hours per fish caught fishing from the shore, and let row A represent hours per fish caught using a boat. The following data are paired by month from October through April. (Data in pictures)

Suppose that for a test of proportion we have :p=0.5 and . The test statistic z=1.53 and the p-value is reported as P-value = 0.063. Find the error in the reasoning.     This is a right-tailed test so the P-value should be 0.9370.     This is a two-tailed test so the P-value should be 0.126.     The P-value should have been calculated using the studentâ s t-distribution.     There is no error in the reasoning.     None of these.
