Aileen has 10 apples. How many apples will there be in 7 boxes?

Marysya12 [62]

The answer should be 1 because you can’t box up pieces of apples to divide it perfectly into a box. It matters that each box has a full apple!! Hope this makes sense!!

What is the range of P-values for the test? The range of P-values for the test is ▼ Based on the results, does the distribut

Vera_Pavlovna [14]

Answer:

1. The main objective of the study is to test the claim that the distribution of fatal injuries for cyclists wearing helmets and those without

Null hypothesis: the distribution of fatal injuries for cyclists who do not wear a helmet remains the same distribution for all other cyclists

alternative hypothesis: the distribution of fatal injuries for cyclists who do not wear a helmet does not follow the same distribution for all other cyclists.

for the null hypothesis, the formula for the expected frequency is shown below

E=n*p

E=2075*p

Location of Injury Observed Count Probability p Expected Count

Multiple Locations 1044 0.57. 1182.75

Head 868 0.31. 643.25

Neck 35 0.03. 62.25

Thorax 81 0.06. 124.5

Abdomen/lumbar/ 47 0.03. 62.25

spinem. N=2075

according to the data obtained from the table see graphic 1

P value = 0.0

level of statistical significance Alpha= 0.01

null hypothesis will be rejected if p <0.01

so if we have a p value of 0.0 we can reject the null hypothesis with a significance level of 1%

Correct:

B. Reject Upper H 0. There is sufficient evidence that the distribution of fatal injuries for riders not wearing a helmet does not follow the distribution for all riders.

2. Correct

B. Motorcycle fatalities from head injuries occur more frequently for riders not wearing a helmet.
