During an experiment, a spinner landed on green 9 times, which resulted in an experimental probability of StartFraction 1 over 6

EndFraction. Mary said that there must have been 45 trials in the experiment. Why is Mary incorrect?
If there were 9 occurrences and 45 trials, the simplified experimental probability would be One-fifth, not StartFraction 1 over 6 EndFraction.
Mary multiplied the 9 occurrences by 6 instead of 5.
Mary mistakenly thought that StartFraction 1 over 6 EndFraction was the simplest form of StartFraction 9 over 45 EndFraction.
If there were 9 occurrences, the simplified experimental probability would be StartFraction 1 over 7 EndFraction, not StartFraction 1 over 6 EndFraction.

Vitek1552 [10]

Answer:

107.50

Step-by-step explanation:

Given the following :

Midpoint (S)____F

S y 93 95 97 99 101 103 105 107 109 111 f 19 25 38 17 12 10 5 4 4 2

Calculating the mean and standard deviation using a calculator :

The mean(m) of the data above = 98.12

Standard deviation (sd) = 4.02

Proportion = 99% of population

From z table = 2.33

Using :

Zscore =(x - m) / sd

2.33 = (x - 98.12) / 4.02

2.33 * 4.02 = x - 98.12

9.3666 = x - 98.12

9.3666 + 98.12= x

x = 107.4866

X = 107.50
