Answer:
3/2
Step-by-step explanation:
The ratio of males to females in a cycling club is 5:3.
1/3 of the males are under 18
2/9 of the females are under 18
The fraction of the club members that are under 18 is calculated as:
Male: Female = Male/Female
We are told in the above question:
1/3 of the males are under 18
2/9 of the females are under 18
Hence:
1/3 / 2/9
= 1/3 ÷ 2/9
= 1/3 × 9/2
= 3/2
The fraction of the club members that are under 18 is 3/2
To answer this you need to read the stem and leaf lot and determine how many values were over 28., Or how many were less than or at 28 and subtract it from 30.
There are 10 teams at 28 or less, so 20 teams are above 28.
The number to the left of the | tells us the tens place of the set of number that come after it.
For example 2|4 7 8 stands for 24, 27, and 28.
If 20 out of 30 were above 28 homeruns, then your probability is 20/30 or 2/3 or 0.667.
Answer:
a. 1.645 multiplier = 5% critical value
b. 95
Step-by-step explanation:
Note that in statistical analysis probability principles are often used. The critical value from the critical region indicates whether the statistician should reject or accept the null hypothesis.
Note that the confidence multiplier is a constant that shows the number of standard deviations in a normal curve; the deviation standard<em> implies the measure of difference between the observed value of a variable and some another value.</em>
