Aresearcher conducts a two–independent sample t-test with a sample of 24 participants, where 12 participants are observed in each group. what are the degrees of freedom for this hypothesis test?

22

Step-by-step explanation:

here we have given 12 participants in each group so

we have to find the degree of freedom of this hypothesis

we know that degree of freedom of hypothesis is given by

so by using this formula

degree of freedom of hypothesis = =12+12-2=22

so the degree of freedom of hypothesis will be 22

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

answer: 1 + 1 = 11
