About 73% of the residents in a town say that they are making an effort to conserve water or electricity. One hundred residents are randomly selected. What is the probability that the sample proportion making an effort to conservewater or electricity is greater than 79%? Interpret your result. Assume the sampling distribution of sample proportions is a normal distribution. The mean of the sample proportion is equal to the population proportion and the standardpqdeviation is equal tonThe probability is(Round to four decimal places as needed.)

The given data is as follows:Population proportion of residents who are making efforts to conserve…

Eighty-three percent of adults in a certain country believe that life on other planets is plausible. You randomly select five adults and ask them whether they believe that life on other planets is plausible. The random variable represents the number of adults who believe that life on other planets is plausible. Find the mean, variance, and standard deviation of the binomial distribution for the random variable. Interpret the results find the mean, variance, and standard deviation
The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample ofn=70, find the probability of a sample mean being less than 24.2 if p = 24 and o= 1.23. Click the icon to view page 1 of the standard normal table. Click the icon to view page 2 of the standard normal table. For a sample of n = 70, the probability of a sample mean being less than 24.2 if u = 24 and o = 1.23 is (Round to four decimal places as needed.) Would the given sample mean be considered unusual? The sample mean be considered unusual because it has a probability that is than 5%.
