Selected Technologies According to recent surveys, 60% of households have personal computers. If a random sample of 192 households is selected, what is the probability that more than 60 but fewer than 102 have a personal computer? Round z-value calculations to 2 decimal places and final answer to at least 4 decimal places. P(60

Find the indicated probability and interpret the result. From 1975 through 2020, the mean annual gain of the Dow Jones Industrial Average was 653. A random sample of 34 years is selected from this population. What is the probability that the mean gain for the sample was between 400 and 800? Assume o = 1540. The probability is (Round to four decimal places as needed.) Interpret the result. Select the correct choice and fill in the answer box to complete your choice. (Round to two decimal places as needed.) O A. About OB. About OC. About OD. About % of samples of 46 years will have an annual mean gain between 400 and 800. % of samples of 34 years will have an annual mean gain between 653 and 800. % of samples of 34 years will have an annual mean gain between 400 and 800. % of sampl of 34 years will have an annual mean gain between 400 and 653.

In a brand recognition study, 1014 consumers knew of Gap, and 6 did not. Use these results to estimate the probability that a randomly selected consumer will recognize Gap.Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. prob =         %

You host a house party with 4 guests attending. Every guest gets a chance to win a gift by spinning a wheel with 1/3 of a chance of stopping at the winning spot. If you prepare 2 gifts to give away, what is the probability of you being embarrassed for running short of gifts (i.e, there are more winners than the number of gifts). Round your answer to two decimal places (for example: 0.12)

A population proportion is 0.58. Suppose a random sample of 658 items is sampled randomly from this population.   what is the probability that the sample proportion is between 0.53 and 0.56? What is the probability that the sample proportion is less than 0.49?
