The number of chocolate chips in an 18 -ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (a) What is the probability that a randomly selected bag contains between 1100 and 1400 chocolate chips, inclusive? (b) What is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) What proportion of bags contains more than 1200 chocolate chips? (d) What is the percentile rank of a bag that contains 1450 chocolate chips? (a) The probability that a randomly selected bag contains between 1100 and 1400 chocolate chips, inclusive, is (Round to four decimal places as needed.)

Use the sample data and confidence level given below to complete parts (a) through (d). A drug is used to help prevent blood clots in certain patients. In clinical trials, among 4140 patients treated with the drug, 137 developed the adverse reaction of nausea. Construct a \( 90 \% \) confidence interval for the proportion of adverse reactions. a) Find the best point estimate of the population proportion p. (Round to three decimal places as needed.)

Express the confidence interval \( 0.111<p<0.777 \) in the form \( \hat{p} \pm E \).

Calcúlese el estimador máximo-verosímil del parámetro \( \lambda \) la distribución de Poisson en muestras aleatorias simples de tamaño \( n \).

You are a journalist working on an article about the nursing profession. Survey data shows that 355 out of 1000 nurses surveyed are considering a different career. If the survey ratio is accurate and there are about 4.8 million nurses registered in the United States, about how many million nurses nationwide are considering a different career?

It is appropriate to model nonlinear relationships using correlational analysis. A) True (B) False
