You and your lab partner record the following counts of stomata in sunflower leaves.

sunflower plant 1 2 3 4 5 6
stomata (per examination area) 88 93 90 92 75 78

(a) calculate the standard deviation of the number of stomata for the sunflower leaves.

(b) calculate the standard error in the number of stomata for the sunflower leaves.

a)

b)

Explanation:

First of all we are required to calculate the mean of the Stomata (per examination area) which is equal to

Now for standard deviation,  the formula is

Where X is the value of number and X' is the value of mean. n is the number of entry.

a)

Substituting the given values in above equation, we get

b) Standard error in the number of stomata for the sunflower leaves.

Standard error =

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
