Ferulic acid is a compound that may play a role in disease resistance in corn.. A botanist measured the concentration of soluble ferulic acid (nmol acid per gm tissue) in corn seedlings grown in the dark or in a light/dark photoperiod. The data are shown in the table below: Sample 1: Dark 92 117 88 91 107 109 100 101 87 87 Sample 2: Photoperiod 111 127 104 115 129 124 123 121 120 117
Suppose the fuel efficiency, in miles per gallon, of a certain model of car is normally distributed. For a random sample of cars of that model, the confidence interval (16.1, 18.1) is generated. Find the margin of error.(round to one decima)

Let π denote some population proportion of interest and suppose a 99% confidence interval for π is calculated to be (0.60, 0.70). Also, suppose we want to test the hypotheses H0:π=0.74 and HA:π≠0.74 . What can you say about the corresponding p-value? The corresponding p-value will be smaller than 0.01. The corresponding p-value will be smaller than 0.05 but larger than 0.01. The corresponding p-value will be larger than 0.05. I can't say anything about the corresponding p-value until I run the test.
Assume we wish to test to see if the mean starting salary of statistics professors is different than the mean starting salary of biology professors: Let Ho: µStat = µBio versus Ha: µStat µBio at the alpha = .05 level of significance and we found the following 95% confidence interval: (126, 610) for µStat - µBio. We would reject Ho. We would Fail to Reject Ho. We would reject Ho based on a 90% confidence interval. We would fail to reject Ho based on a 90% confidence interval. Assume that we use the same sample to construct the 90% confidence interval. Please pick a choice from the following 4 options.
