An agency that hires out clerical workers claims its workers can type, on average, at least 60 words per minute (wpm). To test t

he claim, a random sample of 50 workers from the agency were given a typing test, and the average typing speed was 58.8 wpm. A one-sample tt-test was conducted to investigate whether there is evidence that the mean typing speed of workers from the agency is less than 60 wpm. The resulting p-value was 0.267.
1. Which of the following is a correct interpretation of the p-value?
A. The probability is 0.267 that the mean typing speed is 60 wpm or more for workers from the agency.
B. The probability is 0.267 that the mean typing speed is 60 wpm or less for workers from the agency.
C. The probability is 0.267 that the mean typing speed is 58.8 wpm or less for workers from the agency.
D. If the mean typing speed of workers from the agency is 60 wpm, the probability of selecting a sample of 50 workers with mean 58.8 wpm or less is 0.267.
E. If the mean typing speed of workers from the agency is less than 60 wpm, the probability of selecting a sample of 50 workers with mean 58.8 wpm or less is 0.267.

What’s the value of x?
lozanna [386]

x=13 because you put all of them in an equation and set them equal to 180 bc that is how many degrees are in a triangle so it would be 6x+19+5x-15+3x-6=180 and then you solve the equation so it would be 14x-2=180 then you would add to to both side which would cancel out on the left and make 182 on the right then divide 182 by 14 and you get 13.
