According to a survey about how workers get to work in Wyoming, 77 percent of workers get to work by driving alone, 11 percent get to work by carpooling, 4 percent get to work by walking, and 8 percent get to work by other means of transportation. Suppose a sample of 200 Wyoming workers is selected at random. Let the random variable \( D \) represent the number of workers in the sample who get to work by driving alone. What is the expected value of \( D \) ? A company that ships crystal bowls claims that bowls arrive undamaged in 95 percent of the shipments. Let the random variable \( G \) represent the number of shipments with undamaged bowls in 25 randomly selected shipments. Random variable \( G \) follows a binomial distribution with a mean of 23.75 shipments and a standard deviation of approximately 1.09 shipments. Which of the following is the best interpretation of the mean? (A) Every shipment of 25 bowls will have 23.75 undamaged bowls. (B) Every shipment of 25 bowls will have 23.75 damaged bowls. (C) On average, the company receives 23.75 shipments before receiving the first shipment with a damaged bowl. (D) For all possible shipments of size 25 , the average number of damaged shipments is (E) For all possible shipments of size 25 , the average number of undamaged shipments is 23.75 . arnal th 7275 2 -value corresponding to \( 95 \% \) 5. a) La mediana del conjunto de datos \( 16,5,11,19, x, 4 \) es 9. Calcula el valor de \( x \). 14 Voici des informations concernant le nombre de personnes infectées par l'influenza dans deux villes différentes. \[ \begin{array}{lll}\text { Ville (A) }\end{array} \] - Initialement, 12 personnes sont infectées. - Le nombre de personnes infectées augmente de \( 25 \% \) par jour. Th class mean Given that the mean of the numbers tanda \( 8,9, x,(x+3) \) and 18 is 11 , find the \( =\sqrt{2} \) (a) Vadue of \( x \) (b) standerd deviation. Which digit has 3 significant digits? 0.001 1.012 1.01 0.025 Assume that the following confidence interval for the difference in the mean length of male (sample 1 ) and female babies (sample 2) at birth was constructed using independent simple random samples. What does the confidence interval suggest about the difference in length between male babies and female babies? -0.2 in. \( <\mu_{1}-\mu_{2}<1.7 \) in. A. Male babies are longer. B. Female babies are longer. C. There is no difference in the length between male and female babies. Analiza y resuelve cl siguiente problema En un salón de clases hay 40 estudiantes. A 25 les gusta el helado de fresa y a 30 les gusta el helado de chocolate. Si a 10 estudiantes no les gusta ni el helado de fresa ni el de chocolate, ¿cuántos estudiantes les gustan los dos helados?
