HELP ASAP

AND IF YOU COULD EXPLAIN, THATD BE GREAT

-41

Step-by-step explanation:

the problem is basically saying that we need to first substitute 5 in for x in the f(x) function first.

then we need to take that answer that we got and substitute it for x in the g(x) function.

i will do this step by step for you

start with the f(x) function

f(x) = 4x + 3

substitute 5 in for x

f(x) = 4(5) + 3

solve

f(x) = 20 + 3

f(x) = 23

now we use our answer from the f(x) function we just solved, and we put it into the g(x) function.

basically you are going to now substitute 23 for x in the g(x) function.

i will also do this step by step for you.

take the g(x) function

g(x) = -2x + 5

substitute 23 for x

g(x) = -2(23) + 5

solve

g(x) = -46 + 5

g(x) = -41

so now your overall answer is -41.

hope this helped good luck <3

Hence, data does not suggest the true average gap detection threshold for CTS subjects exceeds that for normal subjects.

Step-by-step explanation:

H0 : μ1 = μ2

H1 : μ1 < μ2

Given :

m = 8 ; x1 = 1.71 ; s1 = 0.53

n = 10 ; x2 = 2.53 ; s2 = 0.87

The test statistic :

(x1 - x2) / √(s1²/m + s2²/n)

(1.71 - 2.53) / √(0.53²/8 + 0.87²/10)

-0.82 / √0.1108025

Test statistic = - 0.82 / 0.3328700

Test statistic = - 2.463

The degree of freedom using the conservative approach :

Smaller of (10 - 1) or (8 - 1)

df = 7

TCritical value(0.01, 7) = 2.998

Decision region :

Reject H0 if |Test statistic| > |critical value|

Since, 2.463 < 2.998 ; WE fail to reject H0 ; Hence result is not significant at α = 0.01
