Question

the main charge for satellite television for example of a household was $18.50 per month was a standard deviation of $14.50 per month. estimate the percent of satellite televisions changes between $73.00 and $102.00

Answer 1

To estimate the percentage of satellite television charges between $73.00 and $102.00, we can use the concept of standard deviation.

1. Calculate the Z-scores for both values using the formula:
Z = (X - μ) / σ
where X is the value, μ is the mean, and σ is the standard deviation.

For $73.00:
Z1 = (73.00 - 18.50) / 14.50

For $102.00:
Z2 = (102.00 - 18.50) / 14.50

2. Use a Z-table or a statistical calculator to find the corresponding percentile associated with each Z-score. This will give us the percentage of values below each value.

Let's assume that Z1 corresponds to P1 and Z2 corresponds to P2.

3. To estimate the percentage between these two values, subtract P1 from P2 and multiply by 100:
Percentage = (P2 - P1) * 100

Please note that without the specific distribution of charges (e.g., normal distribution), we cannot provide an exact figure. The estimation above assumes a normal distribution, which might not be accurate in this specific case.
