And we can find this probability like this:
b)
And using the z score we got:
c)
And if we use the continuity correction we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Continuity correction means that we need to add and subtract 0.5 before standardizing the value specified.
Part a
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where and
Part a
For this case we want to find this probability:
And if we use the z score given by:
We got this:
And we can find this probability like this:
Part b
For this case we want this probability:
And if we use the continuity correction we got:
And using the z score we got:
Part c
For this case we want this probability:
And if we use the continuity correction we got:
ACCORDING TO QUESTION:-
Cucumbers = 6 for $2
Peppers = 12 for $9
Tomatoes = 6 fir $4
____________
SO NOW
____________
____________
For 9 cucumbers = as 6 cucumbers is for $2 then 9 will be of $3........1️⃣
For 18 peppers = as 12 peppers are for$9 so 18 will be of $12.........2️⃣
For 21 tomatoes =as 6 tomatoes are for $4 then 21 tomatoes are $14 .......3️⃣
Now add 1️⃣ +2️⃣ + 3️⃣
here $3 +$12 + $14= $29
HOPE IT HELPED YOU.
