please help this probability and statistics, thanks

1G. Concrete strength is usually related to its strength at 28 days based on the load that a standard cube of concrete can sustain when tested in compression in a compression testing rig. The data below contains the results for a series of 40 concrete strength tests undertaken on a construction project currently being developed by your company. Data Data Cube No. fc (N/mm?) Cube No. fc (N/mm2) 36.64 21 23.47 N 40.96 22 34.29 W 27.42 23 32.09 4 24.12 24 24.89 5 41.44 25 25.67 34.94 26 33.78 J 25.32 27 38.61 00 41.14 28 37.23 9 37.36 29 31.31 10 31.64 30 26.39 11 41.42 31 24.39 12 37.53 32 42.99 13 23.34 33 32.69 14 36.43 34 38.16 15 31.81 35 36.49 16 33.65 36 42.87 17 33.88 37 41.54 18 38.19 38 28.61 19 24.79 39 37.37 20 24.81 40 30.22 You are required to summarise this data and calculate the following: i. the mean strength ii. the median strength iii. the standard deviation for the results iv. the percentage of blocks which fall between +/- one standard deviation v. estimate the probability that the strength of a given concrete cube will exceed 37 N/mm vi. apply binomial distribution methods to determine the probability of testing a cube which will exceed 37 N/mm within the next 5 tests
