Step-by-step explanation:
Given : A biologist studied how cells grow by adding liquid protein to cell samples.
She divided of an ounce of liquid protein evenly among 3 cell samples.
Here , total quantity of liquid protein = of an ounce
Total cell samples = 3
Now , Quantity of liquid protein given by her to each cell = (total quantity of liquid protein ) ÷ (3)
= .
Hence, Quantity of liquid protein given by her to each cell =
Answer:
d. 90 cm, 1.2 cm
Step-by-step explanation:
Given that:
The sample size n = 36
For the length of the link:
The mean = 2.5
The standard deviation s = 0.2 cm
In a chosen 36 links, The mean and standard deviation for the length chain is as follows:
Mean = n
Mean = 36×2.5
Mean = 90 cm
The Standard deviation = s×√n
The Standard deviation = 0.2×√36
The Standard deviation = 0.2×6
The Standard deviation = 1.2 cm
