Question

22) The amount of snowfall falling in a certain mountain range is normally distributed with a mean of 22) 89 inches, and a standard deviation of 14 inches. What is the probability that the mean annual snowfall during 49 randomly picked years will exceed 91.8 inches? A) 0.5808 B) 0.0808 C) 0.0026 D) 0.4192 he given values are di screte. Use the continuity correction and describe the region of the normal distribution that orresponds to the indicated probability 23) The probability of more than 56 correct answers 23) A) The area to the left of 56.5 C) The area to the right of 56 B) The area to the right of 55.5 D) The area to the right of 56.5 24) 24) The probability of at least 42 boys A) The area to the right of 41.5 C) The area to the right of 42 B) The area to the right of 42.5 D) The area to the left of 41.5 t uitable to uee the normal

Explanation / Answer

22)

P(X>91.8)=P(Z>(91.8-89)/(14/(49)1/2) =P(Z>1.4)=0.0808
