Description
As a result of the experiment, data were obtained recorded as a statistical series. Required:
a) record the values of the experimental results in the form of a variation series;
b) find the range of variation and divide it into 9 intervals;
c) build a frequency polygon, a histogram of relative frequencies and a graph of the empirical distribution function;
d) find the numerical characteristics of the sample x, DB;
e) accepting as a null hypothesis H0: the general population from which the sample is extracted has a normal distribution, check it using Pearson's test at a significance level of α = 0,025;
f) find the confidence intervals for the mathematical expectation and the standard deviation with a reliability γ = 0,9.
