Grades on a standardized test are known to have a mean of 940 for students in the united states. the test is administered to 436 randomly selected students in florida; in this sample, the mean is 952.22 and the standard deviation (s) is 101.52. the 95% confidence interval for the average test score for florida students is ( nothing, nothing). (round your responses to two decimal places.) is there statistically significant evidence that florida students perform differently than other students in the united states? the 95% confidence interval for the average test score for florida students â–ľ mu = 940, so the null hypothesis that mu = 940 (that florida students have the same average performance as other students in the united states) â–ľ at the 5% level.

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
