A Level Maths Statistics Year 1 Chapter 7: Mini test

What is the correct calculator input for X~B(30,0.2) and P(X<25)?

• CD x=30 N=25 p=0.2
• CD x=25 N=30 p=0.2
• PD x=25 N=30 p=0.2
• CD x=24 N=30 p=0.2

A hypothesis test for the Binomial is always for

• n, number of trials
• p, the probability of success
• the mean
• the correlation

Which are possible hypotheses for the probability?

• H₀: x=0.3 H₁: x>0.3
• H₀: p=0.3 H₁: μ≥0.3
• H₀=0.3 H₁>0.3
• H₀: p=0.3 H₁: p>0.3

The probability you found is smaller than the level of significance...

• Accept H₀
• Reject H₀
• Reject H₁
• Accept H₁

What do you not need to include in your solution to a hypothesis test

• Compare your prob to level of significance
• State whether you Accept or Reject H₀
• Give a contextual statement
• Trick question. I need to include all of these
