The answer for the completion exercise shown above is the second option (option b), which is:
b. critical value.
Therefore, you have that the text is: "<span>A critical value is a numerical quantity computed from the data of a sample..."
</span>
This numeral quantity is used in statitics. Then, if the absolute value is greater that the quantity defined before, the null hypothesis must be rejected.
Answer:
Step-by-step explanation:
If Marios share is 3 parts and is £96, then
Find one part = 96/3 = 32
So,
Rachel receives = 32 x 4 = £128

Answer:
The data provide strong evidence that young men weigh more on average than old men in the U.S
Step-by-step explanation:
Given :
The null hypothesis ; H0 : μ1 = μ2
The alternative hypothesis ; H1 : μ1 > μ2
T score = 5.3 ; Pvalue = < 0.0001
The decision region :
If Pvalue < α ; We reject the Null
If Pvalue > α ; We fail to reject the Null
When the α - level isn't stated, we usually assume a α - level of 5%
However, even at lower alpha level of 1% = 0.01 ;
The Pvalue < α
Hence, we can conclude that there is significant evidence that there is difference in the mean weight of young men and old men in the U.S
Answer:
Probability weightlifter hurts his back = 0.3875 i.e 38.75%
Step-by-step explanation:
Probability of using right body form = 75%
Probability of using bad body form : 1 - Prob (right body form) = 1 - 75% = 25%
Probability of getting injured if right body form = 20%
Probability of getting injured if using bad body form = 95%
- Probability of getting injury :
Prob (Right body form & injury) or Prob (wrong body firm & injury)
(0.75) (0.20) + (0.25) (0.95)
0.15 + 0.2375
= 0.3875 i.e 38.75%
