Animal scientists studied foraging behavior of the scrub lizard, found in central Florida. Foraging is the process of searching for food. To study such behavior, the scientists recorded the number of head
movements per minute for a sample of 63 lizards. A 95 percent confidence interval constructed from the
sample is given as 2.7 +0.62 head movements per minute.
Based on the interval, is a claim of 3 head movements per minute plausible?
A
The claim is not plausible because 3 head movements per minute is contained within the
interval
B
The claim is not plausible because 3 head movements per minute is not contained within
the interval
с
The claim is not plausible because 95 percent of 3 is greater than the sample mean of
2.7.
D
The claim is plausible because 3 head movements per minute is not contained within the
interval
E
The claim is plausible because 3 head movements per minute is contained within the
interval

In the lab, I conducted tests and observed the physical properties of minerals. I combined my observations to identify the mineral samples based on their hardness, streak, color, and luster, and on how they break. I also identified rock samples based on their physical properties, such as grain size and foliation. I learned that the properties that are used to classify or group minerals and rocks can also be used to identify them. I also learned that the physical properties of rocks can tell us how they were formed.

explination: i took the test
