I need the same answer but change some words
The value used is mean the estimator. The average of thepopulation can be estimated punctually by the mean of the sample:.
The proportion of the population can be estimated punctually by theproportion of the sample: . The standard deviation of thepopulation can be estimated punctually by the standard deviation ofthe sample, although there are better estimators: . Point ofestimate for mean calculated is 36.4.
The normal distribution is the continuous distribution that is mostcommonly used in statistics. Many continuous variables common inthe business world have distributions that closely resemble thenormal distribution. The normal distribution serves to approachdifferent distributions of discrete probability, such as thebinomial distribution and the Poisson distribution. The normaldistribution provides the basis for classical inferentialstatistics by its relation to the central limit theorem. In thenormal distribution, one can calculate the probability that severalvalues ??will occur within certain ranges or intervals. However,the exact probability of a particular value within a continuousdistribution, such as the normal distribution, is zero.
The standard normal distribution, or typified or reduced, is thatwhich has the mean value zero, ? = 0, and by standard deviation theunit, ? = 1. The probability of the variable X will depend on thearea of ??the enclosure shaded.
