sara y su hermana alejandra, tienen que ir al mercado a comprar. saben que una sandía les cuesta q 10.00, un banano q 2.00, una manzana q 1.00, una docena de aguacates q 36.00. si su mamá les pide que compren: una sandía, una docena de bananos y 2 aguacates, ¿cuánto gastarán?

40.00

Step-by-step explanation:

una sandia 10.00

un banano 2.00

un aguacate 3.00 (porque una docena equivale 12 artículos; 36/12 es 3)

una sandía 10.00

una docena de bananos 12(2.00) = 24.00

dos aguacates 2(3.00) = 6.00

10.00 +24.00 +6.00

=40.00

The correct option is (A).

Step-by-step explanation:

A two -sample t-test is used to determine whether there is significant evidence that students at University 1 drink more than students at University 2.

The hypothesis can be defined as follows:

H₀: The students at University 1 does not drink more than students at University 2, i.e. μ₁ ≤ μ₂.

Hₐ: The students at University 1 drink more than students at University 2, i.e. μ₁ > μ₂.

The information provided is:

test statistic (t) = 2.64

p-value = 0.005

The p-value of the test is very small for all the commonly used significance level. The null hypothesis will be rejected.

Conclusion:

The samples provide significant evidence that students at University 1 drink more than students at university 2.

Thus, the correct option is (A).
