Can I please have help with the histogram

3. An engineer measured the Brinell hardness of 25 pieces of ductile iron that were sub-critically annealed. The resulting data were: 156 103 167 174 179 179 187 183 156 187 156 179 185 179- 179 174 179 170 156 174 170 487 Make a Histogram of the data Make a table with the mean, standard deviation and the 5 number summary Are assumptions for normality met? The engineer believes that the hardiness is greater than 170. Based on this sample, can he conclude that it is greater (a = 0.05)? 156- 4 170 - 3 187-3 189 - 1 174- 3 163 - 1 179- 6 167- 2 183- 2 Bing Quartile ! Median Quartile 3 Standard Mean Devation 172.52 167 174 179 10.13 culator put bata M 4 , 4 , 2 25 172.52 = 10.31 1-22 alme= 0-117 Il to reject the null hypothesis, There is insufficient evidence to at the hardness of the iron is greater than 1 to
