of the F distribution: (3) Example: We want to measure the monthly sales volume from Microsoft and Apple. We collect data for a year ( 12 months). We calculate the variance for both and define the “degrees of freedom’ (n-1= 11) and then we can build the F-distribution. F statistic (): Defined as the ratio of the dispersions of the two distributions‚ in other words it is the value calculated by the ratio of two sample variances . F always >=1. The F statistic can test the null hypothesis:

Increasing the alpha level (for example‚ from α=0.01 to α= 0.05) Increases the probability of a Type I error. Increases the size of the critical region. Increases the probability that the sample will fall into the critical region. Samples of size n = 16 are selected from a population with μ=

Bootstrapping (In Statistics)? Bootstrapping is an interesting process or technique of assigning measure of accuracy. Depended upon calculation‚ Bootstrapping can be used to any statistic to measure estimation. Definition According to the Cambridge dictionary of statistics – “A confidence interval is a range of values‚ calculated from the sample observations that are believed‚ with a particular probability‚ to contain the true parameter value. A 95% confidence interval‚ for example‚ implies that
