Answer:
Test is Left tailed test
Parameter tested is standard deviation
Step-by-step explanation:
We are given the hypothesis as;
Null hypothesis; H0: σ = 8.6
Alternative hypothesis; H1: σ < 8.6
Where;σ is a constant generally known in statistics as the standard deviation.
Now, it's the alternative hypothesis that will let us know whether this is left tailed, right tailed or two tailed.
Alternative hypothesis says σ < 8.6.
This means that the values of σ that satisfy this hypothesis are less than 8.6 and thus are on the left hand side of 8.6 on a number line. Thus, the shaded region in a normal distribution curve will be on the left.
Thus, it's a left tailed test
Staircase one looks like our normal staircase we have today which looks like it’s easier so staircase two is more difficult to walk up?
But also
staircase one will be harder because it’s just smaller? Shorter and less space for your feet to step on. Staircase two has 1 ft of space for your feet to land on and is a bit higher which seems like normal stairs? But if I go measure my staircase... I don’t think it’s 1 ft... so? Maybe it’s staircase one? I’m sorry if I’m confusing you!!
I don’t think that’s a right or wrong question? Maybe it’s just your opinion? I’m so sorry, I honestly have no clue
Answer:
There are 210 different ways that 4 cards can be drawn.
There are 252 different ways that 5 cards can be drawn.
There are 120 different ways that 7 cards can be drawn.
Step-by-step explanation:
Use the combination formula
10C4 =210
10C5 = 252
10C7 = 120
