The standard deviation of the given data is 3.5
<h3 /><h3>How to calculate the standard deviation of data?</h3>Standard deviation is used to determine the rate of dispersion of data with respect to the mean.
The formula for calculating the standard deviation of data is given as:
Given the data below:
10.4, 10.3, 11.7, 11.1, 8, 4.4, 2.6, 1.8, 2.5, 4.4, 7.3, 9.5
Using the stdevp calculator the standard deviation is calculated as:
σ = √12.405
σ = 3.5
Hence the standard deviation of the given data is 3.5

The value of y in the given logarithmic equation is 3. The correct option is C. 3
<h3>Evaluating Logarithmic equation </h3>From the question, we are to determine the value of y in the given logarithmic equation
The given equation is
By applying one of the laws of logarithm, we get
Now, express 64 in index form,
Since the bases are equal, we can equal the powers to get
3 = y
∴ y = 3
Hence, the value of y in the given logarithmic equation is 3. The correct option is C. 3
