Find the​ range, variance, and standard deviation for the given sample​ data, if possible. If the measures of variation can be o

btained for these​ values, do the results make​ sense? Biologists conducted experiments to determine whether a deficiency of carbon dioxide in the soil affects the phenotypes of peas. Listed below are the phenotype​ codes, where 1equals=​smooth-yellow, 2equals=​smooth-green, 3equals=wrinkled ​yellow, and 4equals=​wrinkled-green.

4. After measuring the mass of water, the data is averaged and it is determined that the mean of 4 measurements is 122.4 g with
pogonyaev

The mass of the object would be the mean which is 122.4, which must be rounded to three significant figures, i.e 122 g.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

After measuring the mass of water,

the data is averaged and it is determined that the mean of 4 measurements is 122.4 g with a standard deviation of 1.3 g.

If the deviation is 1.3 g then, the true measurement will be

122.4g - 1.3g to 122.4g + 1.3g:

Lower limit: 122.4 g - 1.3 g

                     = 121.1 g

Upper limit: 122.4 g + 1.3 g

                  = 123.7 g

only the first two digits, hundreds and tens places, are certain.

The one digit is uncertain.

It should report the number with three significant figures:

2 certain digits + 1 uncertain digit.

The mass of the object would be the mean which is 122.4,

which must be rounded to three significant figures, i.e 122 g.
