Answer:
The answer is
Step-by-step explanation:
After operating under these conditions for a period of 6 months, he selects a simple random sample of 15 days. He logs the hours he walked each day as tracked by his fitness monitor, alongside his recorded billable hours from a work application on his computer.
The calculated slope is -0.245
The number of samples is n = 15
The standard error is 0.205
The confidence level is 95
The significance level is (100 - 95)% = 0.05
The degrees of freedom is n - 2 = 15 - 2 = 13
Critical Value = 2.16 = [using excel = TINV (0.05, 13)]
Marginal Error = Critical Value * standard error
= 2.16 * 0.205
= 0.4428
From 1991 to 2000, Kentucky's average annual temperatures (°F) were recorded as 57.5, 55.1, 52.2, 55.6, 55.6, 54.4, 54.5, 58.3, 57.3, and 55.7.
We will assess the measures of center.
To begin with, we will compute the mean.
Mean = (Total of all observed values) / (Number of observations)
Mean =
=
= 55.62
Next, we will determine the mode.
Mode signifies the number that appears most frequently within a set.
Considering the data set 57.5, 55.1, 52.2, 55.6, 55.6, 54.4, 54.5, 58.3, 57.3, and 55.7.
Mode = 55.6
Now we will find the median.
First, we will arrange the values in ascending order.
52.2, 54.4, 54.4,55.1,55.6, 55.6, 55.7, 57.3, 57.5, 58.3
With a total of 10 values.
Median = th value
Since the 5th value is 55.6.
Thus, the median stands at 55.6
