Answer:
3 2/3
Step-by-step explanation:
7 1/3 =22/3
3 2/3= 11/3
22-11= 11
11/3= 3 2/3
Let p be the number of green picks added, so we have p green picks and 5+p picks altogether.
We didn’t add any orange picks so we still have 5 orange. Therefore 5/(5+p)=1/3.
Cross-multiplying: 15=5+p so p=10. In all we have 10+5=15 picks.

Answer:
(A) We failed to reject the null hypothesis
Step-by-step explanation:
Given that a high school teacher hypothesized that in her class, boys were taller than girls. If the probability value of her null hypothesis is 0.34, it means:
Here p value is 0.34
This is greater than 0.05 or 0.1 i.e. both for 5% significance and 10% significance.
Whenever p > alpha, we fail to reject null hypothesis
A) We failed to reject the null hypothesis
This would be the correct option
i.e. final conclusion is that there is no significant difference between mean height of girls and mean height of boys at 5% or 10% significance level.
