monitta

Answer:

Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.

We can find sum of all 16 test scores = 84(16) = 1344

Outlier found = 78

If outlier is removed new sum = 1344-78 = 1266

Number of entries without outlier = 15

New average = 1266/12 =84.4

We find that average of new data increases.

Also whenever we remove outlier std deviation also would be reduced.

Walter is practicing his high jumps for the track team. His first jump measured 5 feet, 9 inches. His second jump measured 3 fee

tia_tia [17]

Answer: 1.834 ft

Step-by-step explanation:

Given

Walter's first Jump is 5 ft, 9 in.

His second Jump is 3 ft, 11 in.

We know,

$1\ ft=12\ in$

Converting inches to feet

First Jump in feet

$\Rightarrow 5\ ft+\frac{9}{12}\ ft=5.75\ ft$

Second jump

$\Rightarrow 3\ ft+\frac{11}{12}\ ft=3.916\ ft$

The difference in the measurement of two Jumps is

$\Rightarrow 5.75-3.916=1.834\ ft$

So, Walter first Jump is 1.834 ft higher than the second Jump
