Con los siguientes datos cálcula la varianza muestral: - Lunes: 3 peces - Martes: 2 peces - Miércoles: 4 peces - Jueves: 3 peces - Viernes: 2 peces - Sábado: 5 peces - Domingo: 1 peces

Con los siguientes datos: \( \mathrm{N} / 2: 20 \) \( \mathrm{~L}_{\mathrm{i}:}: 61 \) \( \mathrm{~A}_{\mathrm{i}}: 8 \) \( \mathrm{f}_{\mathrm{a}:}: 10 \) \( \mathrm{f}_{\mathrm{i}:}: 10 \) Encontrar la mediana en datos agrupados.

A normal population has mean \( \mu=62 \) and standard deviation \( \sigma=17 \). (a) What proportion of the population is greater than 103 ? (b) What is the probability that a randomly chosen value will be less than 79 . Round answers to four decimal places. Part 1 of 2

A normal distribution has mean \( \mu=60 \) and standard deviation \( \sigma=20 \). Find and interpret the \( z \)-score for \( x=72 \). The \( z \)-score for \( x=72 \) is \( \square \). So 72 is \( \square \) standard deviations (Choose one) \( \nabla \) the mean \( \mu=60 \).
