The Bureau of Labor Statistics reported that 5% of employed adults in the U.S. held multiplejobs. A random sample of 75 employed adults are chosen,then p is the sample proportion of employed adults with multiple jobs.a) The probability that exactly 6,5% of the employed adults in the sample hold multiple jobs isP(p = 0.065) =b) P(0.04 < p < 0.075)c) P(p > 0.10)=Round the answer to three decimal places.. Round the answer to three decimal places.

4) Smith is a weld inspector at a shipyard. He knows from keeping track of good and substandard welds that for the afternoon shift 5% of all welds done will be substandard. If Smith checks 300 welds completed during that shift, what is the probability that he will find less than 20 substandard welds? A) 0.4066 C) 0.0934 B) 0.5934 D) 0.9066 5) The National Association of Realtors estimates that 23% of all homes purchased in 2004 were considered investment properties. If a sample of 800 homes sold in 2004 is obtained what is the probability that at most 200 homes are going to be used as investment property? A) 0.5935 C) 0.0934 B) 0.4066 D) 0.9099
The national department of epidemiology has calculated the frequency with which flu patients arrive at the country's hospitals. The probability that a patient arrives with the flu is 0.1. Taking into account that the causes of the flu are many in a tropical country, what is the probability that three patients admitted to a hospital all suffer from the flu? What is the correct? A). Because the statistic is national, the probability is 0.3 since the observations can be taken as independent. B). The probability remains at 0.1 since they are independent events, both the flu and the patients. C). The probability is 0.001 since the observations can be taken as independent, since a flu can appear for many reasons throughout a country. D). The conditional probability of receiving a patient with the flu is required given that the first one to arrive had it, therefore it is not possible to calculate the probability.
Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 157 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 41 voted
The standard deviation of monthly rents paid by students in a particular city is assumed to be $ 40. a) If a random sample of 100 students is taken, what is the probability that the sample mean is at least $ 5 higher than the population mean? b) If a random sample of 100 students is taken, what is the probability that the sample mean is at least $ 4 lower than the population mean? c) What should the sample size be so that the probability that the difference between the sample mean and the population mean (negative and positive total) is less than 0.01 $?
A recent study has shown that 28% of 18-34 year olds check their Facebook/Instagram feeds before getting out of bed in the morning,If we sampled a group of 150 18-34 year olds, what is the probability that the number of them who checked their social media before getting out of bed is:a.) At least 30? b.) No more than 54? c.) between 36 and 49 (including 36 and 49)? Use the Normal Approximation to the Binomial distribution to answer this question.

Assume that a report claims that 44% of all ice cream-machines maintain a too high temperature during the summer. You make a survey and examine 122 ice cream-machines in various restaurants. You find that 33 of them maintain a too high temperature a) Calculate the probability of getting the share you received in your sample, given that the results of the report are true at the population level. b) Make a hypothesis test, where you test the hypothesis that the proportion is the one shown by the research report. Use ? = 0.05 c) Interpret the results of your completed hypothesis test in words.
