Answer: t= -1.60
Explanation:
Let be the population mean weight of pigs.
As per given , we have
Sample size : n= 16
Sample mean =
Sample standard deviation :
<em>Since the population standard deviation is not known so the test is a</em><em> t-test.</em>
Test statistic for population mean :
(Substitute all the values.)
Hence, the value of the test statistic needed to test the null hypothesis : t= -1.60
A graph which represents the change in cell surface area to volume ratio with an increasing cell diameter is graph C.
<h3>The ratio of surface area to volume.</h3>Generally, the ratio of cell surface area to volume in living organisms is always required to be very small, so as to allow sufficient materials such as food particles, to move through the cell membrane quickly for the cell's survival and optimum function.
When plotted on the cartesian coordinate, a graph which represents the change in cell surface area to volume ratio with an increasing cell diameter is shown in the image attached below.
