How can i produce random numbers with standard normal distribution and then plot its histogram?

I want to produce 100.000 random numbers(x) with standard normal distribution and then plot its small part(100) and its histogram.

After i want to calculate the statistical parameters of x mean, standard deviation, skewness, kurtosis(interpreting the results)

After, using the data x, i want to create a new data y with unit mean value and 3 standard deviation and plot its histogram.

After, i want to calculate correlation coefficient between x and y.

Finally, if i want to change skewness and kurtosis, what can i do?

Anyone can help me to do these calculation? I will be pleased :) I need help so much.
