To determine the parameter \(\mu\) in this scenario, we need to understand the context of the problem. The problem states that among wheat seeds, \(0.7\%\) are weed seeds. This means that for every 1000 wheat seeds, there are \(0.7\%\) weed seeds.<br /><br />First, let's calculate the number of weed seeds in 1000 wheat seeds:<br />\[ 0.7\% \text{ of } 1000 = \frac{0.7}{100} \times 1000 = 7 \]<br /><br />So, in a random selection of 1000 seeds, 7 seeds are expected to be weed seeds.<br /><br />The parameter \(\mu\) typically represents the mean or expected value in probability and statistics. In this context, \(\mu\) would be the expected number of weed seeds in 1000 wheat seeds.<br /><br />Therefore, the correct answer is:<br />\[ 7 \]<br /><br />So, the parameter \(\mu\) is equal to 7.
