Step-by-step explanation:
Answer:
The sample proportion of printers used in small business is:
The 95% confidence interval for the population proportion of printers that are used in small businesses is:
Where:
is the critical value at 0.05 significance level
Therefore, the 95% confidence interval for the population proportion of printers that are used in small businesses is (0.245 , 0.469)
54 because the formula for the area of triangle is 1/2bh so you just substitute the b and h for 18 and 6
<em>C</em>
Approximately 95% of data falls within 2 standard deviations (±2) of the mean.
<em>Explanation</em>
According to the empirical rule of normal distribution:
Approximately 68% of the data falls within ±1 standard deviation of the mean
2. Approximately 95% of the data falls within ±2 standard deviations of the mean
3. Approximately 99.7% of the data falls within ±3 standard deviations of the mean.
Therefore, among the given options, only option C adheres to the empirical rule of the normal distribution. Therefore, the option C is correct
