Verified
From a sample of 400 items, 14 are found to be defective. The point estimate of the population proportion defective will be:
A) 14
B) 0.035
C) 28.57
D) 0.05
E) 0.26
Point Estimate
A single value (statistic) given as the best guess or most reasonable approximation of a population parameter based on sample data.
Population Proportion
The fraction or percentage of members in a population that exhibit a particular characteristic or attribute.
Defective Items
Goods or products that fail to meet quality standards or specifications and are not fit for their intended use.
- Undertake the computation and clarify the test statistic for hypothesis inquiries related to a singular population mean, a singular population proportion, and the differentiation between two population means or proportions.
Verified Answer
point estimate = number of defective items / sample size
point estimate = 14 / 400
point estimate = 0.035
Therefore, the best choice is B.
