Use the given values of n and p to find the minimum usual value μ - 2σ and the maximum usual value μ + 2σ. n = 290, p = 1/4

answerim :

n

step-by-step explanation:

im not sure but my dad knows

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
