A) Suppose at random 41% of school children develop nausea and vomiting following holiday parties and that you conduct a study to examine this phenomenon, with a sample size of n=42. What is the probability that less than 42 children become sick?

B) Suppose at random 43% of school children develop nausea and vomiting following holiday parties and that you conduct a study to examine this phenomenon, with a sample size of n=43. What is the probability that 34 or less, or 37 or more children become sick?

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...

A random sample of elementary school children in New York state is to be selected to estimate the proportion pp who have received a medical examination during the past year. It is desired that the sample proportion be within 0.035 of the true proportion with a 9999% level of confidence, (Be sure to use four or five decimals of accuracy for all values used in the calculations, including the z-score) (a)    Assuming no prior information about pp is available,...

A random sample of elementary school children in New York state is to be selected to estimate the proportion p who have received a medical examination during the past year. It is desired that the sample proportion be within 0.02 of the true proportion with a 98% level of confidence, (Be sure to use four or five decimals of accuracy for all values used in the calculations, including the z-score) (a) Assuming no prior information about p is available, approximately...

Consider the observations taken on the continuous random variable Y given below. Graph the data using an appropriate plot. Comment on the key features of the graph. Assess the normality of the data set. What do you conclude? Compute the 5-number summary. Treat the sample mean and sample standard deviation as if they are the true population mean and standard deviation. Find P (Y > 90). Treat the sample mean and sample standard deviation as if they are the true...
