Fungus in the air. the air in poultry-processing plants often contains fungus spores. inadequate ventilation can affect the health of the workers. the problem is most serious during the summer. to measure the presence of spores, air samples are pumped to an agar plate and “colony-forming units (cfus)” are counted after an incubation period. here are data from two locations in a plant that processes 37,000 turkeys per day, taken on four days in the summer. the units are cfus per cubic meter of air.27 image fungus image day 1 day 2 day 3 day 4 kill room 3175 2526 1763 1090 processing 529 141 362 224 kill room—processing 2646 2385 1401 866 explain carefully why these are matched pairs data. the spore count is clearly higher in the kill room. give sample means and a 90% confidence interval to estimate how much higher. be sure to state your conclusion in plain language. you will often see the t procedures used for data like these. you should regard the results as only rough approximations. why?

step-by-step explanation:

because it just is

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
