Suppose you are planning to sample cat owners to determine the average number of cans of cat food they purchase monthly. the following standards have been set: a confidence level of 99 percent and an error of less than 5 units. past research has indicated that the standard deviation should be 6 units. what is the final sample required?

 10

Step-by-step explanation:

The formula to find the sample size is given by :-

Given : Significance level :

Critical z-value=

Margin of error : E=5

Standard deviation :

Now, the required sample size will be :_

Hence, the final sample required to be of 10 .

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
