Asample has a mean of m = 39.5 and a standard deviation of s = 4.3, and produces a t statistic of t = 2.14. for a two-tailed hypothesis test with α = .05, what is the correct statistical decision for this sample? (a) the researcher can reject the null hypothesis with alpha = .05 but not with alpha = .01. (b) the researcher can reject the null hypothesis with either alpha = .05 or alpha = .01.(c) the researcher must fail to reject the null hypothesis with either alpha = .05 or alpha = .01.(d) it is impossible to make a decision about h0 without more information.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
