Answer:
There were 20 picks total
Step-by-step explanation:
We can use a proportion to solve this problem. Put the orange picks on top and the total picks on bottom
3 orange 12 orange
-------------- = ---------------
5 total x total
Using cross products
3x = 5*12
3x= 60
Divide each side by 3
3x/3 = 60/3
x = 20
There were 20 picks total
|-6 1/2|, |-1|, |0|, |9|, these are simply going from smallest to largest, once you get past 0 on a number line it goes back by one, for example 0,-1,-2,-3 and so forth, don’t think of negatives like whole numbers
Answer:
0.0445937
Step-by-step explanation:
-Given that the sample statistic has a mean of 406 grams, standard deviation of sq root(225) and the null statistic is 411 grams.
-Assuming normal distribution, the test statistic is calculated as:
-we then find the p-value of the test statistic from the z-tables:
P-value=0.0445937
