(Choose 1 answer)
A manufacturing company wants to compare the mean tensile strength of two different materials used in their products. They collect data from two independent samples: Material A (n=20) and Material B (n=25). After conducting a two-sample t-test, the calculated p-value is 0.10. What decision should the company make regarding the null hypothesis at a significance level of 0.05?
A. Material type will affect to the strength of tensile
B. Material A will have higher strength than Material B
C. Material B will have higher strength than Material A
D. Inconclusive test since the p-value is too small
