Draw a d o the sampling of the sample mean for samples 36 d. For a random sample of what is the chance that the sample wil l the population mean? The probability is 0.0 Round to the decimal places as needed. Use the answers to part and part to find this answer) e. For a random sample of stres, determine the probably that the man weath of the five people obtained will be within 1 ($1 billions of the population mean The probability is 0.83

Answer 1

Ansi Given data, 19, 18, 25, 28119 125. h a so we get mean = wealth 19, 28, 18 189,25 = 21.8 19, 28, 18, 19125 - 21.8 19, 28, 18125125 191281 19,25,25 = 23.2 19118,19,25 125 = 2102 28, 18, 19, 25125 =23 (6) option - (B) is correct one

which sample mean (d) There is no equals sample for population. Thus, for a random sample size of 5, the probability that the sample mean will equal the population mean is zero. Ca e No. of samples for which ample mean is with in $ 1 billions of the population mean & no. of sample for which & (population mean)- a sample mean population means tl) = No. of sample for which & 21.8 s à 223.3 Thus, for a random sample of size 5, the probabilite that the mean wealth of the sive people obtained wine be within $1 billion of the population mean =516 70-833
