Using the following information, calculate the z-statistic for the z-test for one mean. Using the following information, calculate the z-statistic for the z-test for one mean.   = 101 μ = 109   = 3.44 A)  -2.32 B)  2.32 C)  -2.33 D)  2.33 = 101 μ = 109 Using the following information, calculate the z-statistic for the z-test for one mean.   = 101 μ = 109   = 3.44 A)  -2.32 B)  2.32 C)  -2.33 D)  2.33 = 3.44

A) -2.32
B) 2.32
C) -2.33
D) 2.33

Z-test

A method of statistical analysis that evaluates whether there is a significant difference between the means of two populations, given known variances and a large sample size.

µ = 109

Represents the mean (µ) of a dataset or distribution, here specifically stated as 109.

  • Compute the z-statistics for specified datasets.

Final Answer :
C
Explanation :
To calculate the z-statistic, we use the formula:
z = (x̄ - μ) / (σ / √n)
where x̄ is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.
Substituting the given values:
z = (101 - 109) / (3.44 / √1) = -2.33
Therefore, the z-statistic is -2.33, which corresponds to choice C.
