The answer is 0.3.
Tes statistic, z = (X-bar - μ)/σ/√n
Given that X-bar = 0.265, μ = 0.250, σ = 0.35, n = 49
Therefore, z = (0.265 - 0.250)/0.35/√49 = 0.3
What is statistic?
- The study of data gathering, analysis, interpretation, presentation, and organization is known as statistics. In other words, gathering and summarizing data is a mathematical discipline.
- Additionally, statistics might be considered a subfield of applied mathematics. However, uncertainty and variation are two crucial and fundamental concepts in statistics.
- Only statistical analysis can determine the uncertainty and variation in many sectors. The probability, which is a key concept in statistics, essentially determines these uncertainties.
