Question

random 15.8 Ifr is a normal random number with mean 0 and variance 1 (as generated by randn), it can be transformed into a random number X with mean u and standard deviation a by the relation X=ar + In an experiment, a Geiger counter is used to count the radioactive emissions of cobalt 60 over a 10-second period. After a large number of such readings are taken, the count rate is estimated to be nomally distributed with a mean of 460 and a standard deviation of 20 (a) Simulate such an experiment 200 times by generating 200 random numbers with this mean and standard deviation. Plot the histogram (use 10 bins). (b) Repeat a few times to note how the histogram changes each time. Radioactive carbon 11 has a decav Tate k of 0.0338 per minute that is a particu- 15.9

solve with only matlab, please. :)

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries
