i need part 2 answer just To investigate the question of whether the Brinell hardness of two materials A.and Bis different, 10 samples of each of thesematerials were taken and their Brinell hardness was determined. The following values resulted in [HBW]:A. 273.9 295.8 286.5 302.5 300 281.8 291.8 297.6 294.5 311B. 272.9 279.8 275.5 277.5 282 269.8 275.8 272.6 263.5 286The Brinell hardness of both populations can be assumed to be normally distributed.1. Has the materials Aa significantly higher Brinell hardness?Name of the test procedure:Ou test for exact critical valuesOu-test with NV approximationOt-test for dependent samplesO Welch testOt-test for independent samples with homogeneous variancesSignificance level:O 0.5O 0.05O 0.1O 0.01O 0.001Sensible alternative:O H. 2. Has the materials Aa very significantly higher Brinell hardness?Answer:Significance level:O 0.5O 0.05O 0.1O 0.01O 0.001Critical value c:(± 0.02Reason:O if H is assumed at 5%, then also at 1%O Test variable t is greater than the critical value cO Test variable t is less than or equal to cComment:
