For this problem, you must use Excel to perform the necessary calculations. Below are the formulas and equations you will need to use. Click on the image below to download a power point version if the text is blurry or too small.

If it is appropirate to use the binomial distribution, use the formula=binom.dist(number_s,trails,probability,cumulative) to calculate the probability. In this formula, number_s is the number of successful trails, trails is the total number of trails, probability is the probability for a single trail expressed as a decimal, and cumulative should be set as false. This will report the binominal distribution probability for a single outcome. You are tasked with reporting a cumulative probability.

If it is appropriate to use the normal approcimation of the binomial distribution, calculate Z using the correct equation from the option below and then use either the formula = (1-(norm.dist(Z,0,1,TRUE))) when calculating a right-tailed probability or the formula =(norm.dist(Z,0,1,TRUE)) for a left-tailed probability

Right-tailed tests find probabilities for X>_ observed while left-tailed tests find probabiliteis for X =< observed

Question

In Europe, 53% of the flowers of the Rewardless Orchid, Dactylorhiza sambucina, are yellow, whereas the remaining flowers are purple. For this problem, only use the normal approximation where it is appropriate. Use the binomial distribution where the normal approximation is inappropriate.

If we took a random sample of a single individual from this population, what is the probability, reported as a percent, that it would be purple?  

Determine the probability, reported as a decimal rounded to two decimal places, that if we took a random sample of 6 flowers, at least 3 would be purple.

If we took a random sample of 260 individuals, what is the probability, reported as a decimal rounded to four decimal places, that 150 or fewer of the orchids are purple?

A WNba player makes 75% of her free throws. Assume that the player takes 6 free throws during the game. The distribution for the number of made free throws in 6 attempts is.

x || 0 ||    1 || 2 || 3 || 4 || 5 || 6 ||      

P(X) || 0.0002 || 0.0044 || 0.0330 || 0.1318 || 0.2966 || 0.3560 || 0.1780 ||

1. What is the probability of making at making fewer than 3 free throws.

2. What is the probability of making at least 4 of the free throws?

3. What is the mean number of free throws you expect the player to make?

4. What is the standard deviation for the number of free throws made by this player?
