Answer:
The sequence is arithmetic because the terms have a common difference
Step-by-step explanation:
The difference between each term in the sequence is constant. The sequence shown below, considering the y values of the coordinates, are 9, 7.5, 6, 4.5, 3, 1.5. Each term has a difference of 1.5, thus making all terms have a common difference, and making the sequence arithmetic.

Answer:
We reject H₀ , we have enough evidence, women today are taller than in 1990
Step-by-step explanation:
The problem is one tail test. We assume height of women follows normal distribution with σ = 0,5 in.
Then null hypothesis : H₀ ⇒ μ₀ = 63.7
Alternative hipothesis: Hₐ ⇒ μ > 63.7
Significance level 0,05 ⇒ z(c) = 1.645
Statistic z :
z (c) = ( μ - μ₀ ) / (0,5/√45) ⇒ z(c) = (63.9 - 63.7 ) / (0,5 / √45)
z(c) =( 0,2* √45 ) / 0,5
z(c) = 2,68
Evaluation : z(s) > z(c) 2.68 > 1.645
z(c) is in the rejection area we reject H₀
