Answer:
The value of v is 3/4.
Step-by-step explanation:
First, you have to convert mixed number into improper fraction :
In order to find the value of v, you have to substract 3/4 to both sides :
Answer:
Given:
Sample size, n = 11
P = 0.5
a) The shape of the histogram will be symmetrical. This is because the probability of getting heads and tails is equal.
b) The histogram is centered at
p = 0.5 (because of equal probability of obtaining heads and tails).
c) How much variability would you expect among these proportions?
Here, we are to find the standard deviation.
Let's use the formula:
Where
p = 0.5(probability of getting heads)
q = 0.5 (probability of getting tails)
Therefore
= 0.0227 ≈ 0.023
The standard deviation is 0.023
d) A normal model should not be use here because the success/failure condition is violated, since each student only flips the coin 11 times, it impossible to obtain both at least 10 heads and at least 10 tails. Here, the sample size is too small.

True.
All the statements are true.
Step-by-step explanation:
When the data values are increased by 10, the value of the mean, median and mode also increases by 10.
