A survey of 2,450 adults reported that 53% watch news videos. Complete parts (a) through (c) below. a. Suppose that you take a sample of 100 adults. If the population proportion of adults who watch news videos is 0.53, what is the probability that fewer than half in your sample will watch news videos? The probability is that fewer than half of the adults in the sample will watch news videos. (Round to four decimal places as needed.) b. Suppose that you take a sample of 500 adults. If the population proportion of adults who watch news videos is 0.53, what is the probability that fewer than half in your sample will watch news videos? The probability is that fewer than half of the adults in the sample will watch news videos. (Round to four decimal places as needed.) C. Discuss the effect of sample size on the sampling distribution of the proportion in general and the effect on the probabilities in parts (a) and (b). Choose the correct answer below. A. Increasing the sample size by a…
Based on a survey, assume that 39% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when six consumers are randomly selected, exactly two of them are comfortable with delivery by drones. Identify the values of n, x, p, and q.
Salomé is offered to place a $10 bet on a certain event the probability of which happening is estimated to be 70%. In case of the event occurring Salomé will receive a total of $20. Let XX be the Salomé's winnings from the bet. Answer the following questions: 1. Create the probability distribution table for XX : XX outcome payoff xx ,$ P(X=x)P(X=x) win loss 2. Use the probability distribution table to find the following: E[X]=μX=E[X]=μX= dollars. (Round the answer to 2 decimal places.) SD[X]=σX=SD[X]=σX= dollars. (Round the answer to 1 decimal place.)
ssume that 33.2% of people have sleepwalked. Assume that in a random sample of 1454 adults, 523 have sleepwalked. a. Assuming that the rate of 33.2% is correct, find the probability that 523 or more of the 1454 adults have sleepwalked. b. Is that result of 523 or more significantly high?
On average, you receive 2.6 pieces of junk mail a day. Assume that the number of pieces of junk mail you receive each day follows the Poisson distribution. What is the probability that you receive exactly three pieces of junk mail today? A 0.2196 B 0.2167 C 0.1276 D 0.2176
at the bank of california, past data show that 8% of all credit card holders default at some time in their lives. on recent day, this bank issued 12 credit cards to new customers. find the probability that of these 12 customers, eventually a. less than 10 will default b. between 4 to 6 will default
Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 44% of the times when they are needed. A hospital has two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below. a. Find the probability that both generators fail during a power outage. (Round to four decimal places as needed.) b. Find the probability of having a working generator in the event of a power outage. Is that probability high enough for the hospital? Assume the hospital needs both generators to fail less than 1% of the time when needed.(Round to four decimal places as needed.)
A poll reported that 63% of adults were satisfied with the job the major airlines were doing. Suppose 25 adults are selected at random and the number who are satisfied is recorded. Complete parts (a) through (e) below. (c) Find and interpret the probability that at least 20 of them are satisfied with the airlines. The probability that at least 20 adults are satisfied with the airlines is (Round to four decimal places as needed.) Interpret the probability. Select the correct choice below and fill in the answer box within your choice. (Round to the nearest integer as needed.) OA. In 100 randomly sampled surveys of 25 adults, 20 or more of the 25 adults would be expected to be satisfied with the airlines in about B. In 100 randomly sampled surveys of 25 adults, less than 20 of the 25 adults would be expected to be satisfied with the airlines in about OC. In 100 randomly sampled surveys of 25 adults, exactly 20 out of the 25 adults would be expected to be satisfied with the airlines in…

Is that probability high enough for the hospital? Select the correct answer below and, if necessary, fill in the answer box to complete your choice. O A. No, because both generators fail about % of the time they are needed. Given the importance of the hospital's needs, the reliability should…
In an election, suppose that 65% of voters support creating a new fire district. If we poll 220 of these voters at random, the probability distribution for the proportion of the polled voters that support creating a new fire district can be modeled by the normal distibution pictured below. Complete the boxes accurate to two decimal places.

Find the probability that none of the selected adults say that they were too young to get tattoos.
