Answer:
D) All options are True
Step-by-step explanation:
A) t-distribution are symmetrical and uni-modal like Normal the Normal distribution.
B) Normal distribution is said to lack 'uncertainty'. Because of this, its more concentrated on values near the mean, while t-student distributions have more spread values and, as a result, fatter tails.
C) This is true as well, the higher the degrees of freedom, the less uncertainty the t-student has, and they will become as a result, more and more similar to the Normal distribution.
All options are True, so option D is the answer.

Answer:
y = 2x + 7
Step-by-step explanation:
→ Find the gradient
→ Write into y = mx + c format
y = 2x + c
→ Substitute in x = -1 and y = 5
5 = -2 + c ∴ c = 7
→ Write into y = mx + c format
y = 2x + 7
Answer:
5/9
Step-by-step explanation:
What we have in this question are four white balls and 5 red balls.
This is the sample space
[(4w,0R) (4w,1R)(4w,2R)(4w,3R)(4w,4R)(0w,5R)(1w,5R)(2w,5R)
So we have 9 possible sets of events
The event number with the last ball being white = 5
Probability of the last ball drawn being white = 5/9
= 0.56
