Answer

Explanation:

Step1: Identify the formula for proportion

The formula for sample - proportion $\hat{p}=\frac{x}{n}$, where $x$ is the number of successes in the sample and $n$ is the sample size.

Step2: Determine the values of $x$ and $n$

Here, $x = 184$ (number of users planning to upgrade) and $n=250$ (sample size).

Step3: Calculate the sample - proportion

$\hat{p}=\frac{184}{250}=0.736$.

Step4: Convert to percentage

To convert the proportion to a percentage, multiply by 100. So, $0.736\times100 = 73.6%$.

Step5: Round to the nearest percent

Rounding $73.6%$ to the nearest percent gives $74%$.

Answer:

74%
