Answer: 6/40 or 15% chance
Step-by-step explanation:
- 0-39 is a 40 number ratio so chances of getting 2 are 1/40
- 0-4 is a 5 number ratio so chances of getting 2 are 1/5
- you want common denominators so mulriuplethe top and bottom of 1/5 by 5 giving us 5/40
- 5/40 + 1/40= 6/40

Answer:
The observed value of the chi-square statistic is 34.71
Step-by-step explanation:
Given the data in the question';
Calculate the observed value of the chi-square statistic
The chi-square statistic will be;
∑
[ ( O - E)² / E ]
here O is observed frequency of th class
E is expected frequency of th class
= 1, 2 which denote the class of food experts who guess correctly and who didn't guess correctly
so
∈ = n × probability of not guessing correctly = 168 × 2/3 = 112
∈1 = n × probability of guessing correctly 168 × 1/3 = 56
so
∑[ ( O - E)² / E ] = [ ( 92 - 56)² / 56 ] + [ ( 76 - 112)² / 112 ]
= 1296/56 + 1296/112
= 23.14 + 11.57
= 34.71
Therefore, the observed value of the chi-square statistic is 34.71
Answer:
It is 5'10 on the dot
Step-by-step explanation:
You just take 72/12 and then subtract 2 and you get 70 inches which correlates to 5 feet 10 inches.
