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 =

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
