Use Random number generator (under Data Analysis) to simulate the following data set. Create 10 columns, each 20 points long and use the following parameters: Number of variables (10), number of data point (20), Distribution (Normal), Mean (40), Standard Deviation (10), Random seed (1234). The data should be in columns: A,B,C,….,I,J. Randomly pick two columns (say Column B and Column H) and perform 2-sided t-test on these two data columns. Record the P-value and repeat this procedure several times (at...

pipette 50 ml of the approximately 0.004 M potassium permanganate solution to a 250 ml conical flask. Note that this time the permanganate is added to the contents of the flask by pipette rather than from the burette - the principle being that it is present in excess so that the pink colour shou ld remain strongly after the nitrite addition . Using a measuring cylinder , add 25 ml of 2 M sulphuric acid. Pipette 25 ml of the...
