10.41) The strength of concrete depends, to some extent, on the method used for drying. Two different drying methods showed the following results for independently tested specimens (measurements in psi).Note: Please look at the attached imageDo the methods appear to produce concrete with different mean strengths? Use α = 0.05. What assumptions are necessary in order for your answer to be valid? **Method I**- \( n_1 = 7 \)- \( \bar{x}_1 = 3.250 \)- \( s_1 = 210 \)**Method II**- \( n_2 = 10 \)- \( \bar{x}_2 = 3.240 \)- \( s_2 = 190 \)In this comparison of two different methods, we illustrate statistical measures that are crucial for data analysis. Each method lists three key statistics:- \( n \) represents the sample size.- \( \bar{x} \) denotes the mean (average) value of the sample.- \( s \) signifies the standard deviation, which measures the amount of variation or dispersion in the sample.**Graphs or Diagrams:**There are no graphs or diagrams included in this image.

The random variable strength follows normal distribution. There are two independent samples which…

Evaluate the following grades: (Case 1) a grade of 220 points on an exam with u = 200 ando = 21. (Case 2) a grade of 90 points on an exam with µ = 80 and o = 8. * The better grade cannot be determined. The first grade is better. The two grades are equal statistically. The second grade is better.
