Suppose you are planning to study a species of squid at a local wildlife preserve, but out of the 34 locations for which they could be located, only 14 of them contain the species. Due to time constraints, you randomly select 5 locations. What is the probability that 3 of those contain squid and the remaining 2 locations do not contain squid?

Answer #1

X : Number of locations contain squid

n : Number locations selected = 5

Number of locations for which squid could be located = 34

Number of locations contain squid = 14

Probability that randomly selected location contain squid : p = 14/34 = 7/17

q = 1-p = 1-7/17 = 10/17

X follows a Binomial distribution ;

The probability mass function of X :

Probability that 'r' of the selected 5 locations (and remaining 5-r locations do not contain squid) is given by

probability that 3 of those contain squid and the remaining 2 locations do not contain squid = P(X=3)

probability that 3 of those contain squid and the remaining 2 locations do not contain squid = 0.2416

Recall in our discussion of the binomial distribution the research study that examined schoolchildren developing nausea and vomiting following holiday parties. The intent of this study was to calculate probabilities corresponding to a specified number of children becoming sick out of a given sample size. Recall also that the probability, i.e. the binomial parameter "p" defined as the probability of "success" for any individual, of a randomly selected schoolchild becoming sick was given. Suppose you are now in a different...

Suppose you perform a study about the hours of sleep that college students get. You know that for all people, the average is about 7 hours. You randomly select 35 college students and survey them on their sleep habits. From this sample, the mean number of hours of sleep is found to be 6.4 hours with a standard deviation of 0.97 hours. You want to construct a 95% confidence interval for the mean nightly hours of sleep for all college...
