Answer 1

1.

a)

The sample mean is $3gAuZK3e7+0Ln0AAAAASUVORK5CYII=$ = x / n

= (48 + 89+ 49 +26 + 70 + 13 + 1 +57 +88 +59+53 / 11)

= 553 / 11

= 50.3

The Mean is 50.3

b)

Median:
Observations in the ascending order are:
1, 13, 26, 48, 49, 53, 57, 59, 70, 88, and 89

Here, n=11 is odd.

M= value of (n+1 / 2 )^Th observation

    = value of (6 )^th observation

    = 53

The Median is 53

c)

Since each value occurred only once, there is no mode for this data set.

Mode: - There is no mode

Answer: Option B) There is no mode

d)

Mid Range = (max + min) / 2

= (89+1) 2

= 90 / 2

= 45

The Mid Range is 45

The probability of getting someone who tests positive is 23
the probability that did not have the disease is 23 + 129= 152

The probability is 23/152 = 0.151

The probability is approximately 0.151
