A study conducted in June 2015 examines ownership of tablet computers by US adults. A random sample of people were surveyed, and
Tatiana [17]

Answer:

a) The null hypothesis

H₀: P₁ = P₂

The alternative hypothesis

Hₐ: P₁ ≠ P₂

The proportion of the women population that own a tablet is P₁

And the proportion of the men population that own a tablet is P₂

b) The sample statistics are p₁ and p₂ for women and men sample proportions that own a tablet respectively.

p₁ = 0.4663

p₂ = 0.4330

The difference in sample proportion of tablet owners = p₁ - p₂ = 0.4663 - 0.4330 = 0.0333 (not 0)

Hence, the alternative hypothesis is true.

Step-by-step explanation:

The null hypothesis is the one that predicts no difference in tablet ownership.

The alternative hypothesis is the one that proves the initial theory of the survey that there is a difference in the proportion of men and women populations that own a tablet.

If the proportion of the women population that own a tablet is P₁

And the proportion of the men population that own a tablet is P₂

Then, the sample proportion of women that own a tablet = p₁

Sample proportion of men that own a tablet = p₂

The null hypothesis, H₀, stated mathematically, is

H₀: P₁ = P₂

The alternative hypothesis, Hₐ, stated mathematically, is

Hₐ: P₁ ≠ P₂

b) Like I stated in (a) the sample statistics are p₁ and p₂ for women and men sample proportions that own a tablet respectively.

From the data given,

p₁ = (235/504) = 0.4663

p₂ = (197/455) = 0.4330

In the sampled group, the women group have a higher proportion of tablet owners.

The difference in sample proportion of tablet owners = p₁ - p₂ = 0.4663 - 0.4330 = 0.0333

Hence, the alternative hypothesis is true.

Hope this Helps!!!

Table
Lelu [443]

Answer:

A

Step-by-step explanation:

Table:

it says that x is the amount of tickets, so that would be 1, 2, 3, etc.

It says that y is the money spent and also tells us that one ticket is $3, so obviously the money would be increasing by thirds: 3, 6, 9

This all goes with the first table (table A)

Graph:

As for the graph-

X = # of tickets (1, 2, 3)

Y = $ spent (3. 6, 9)

The answer would be graph A, because when looking at it you can tell that the starting point is at $0 for 0 tickets, unlike for graph b, which shows $3 for 0 tickets, which does not make any sense. But when you continue on when graph A, you can tell that this answer choice is correct, because every time, the y value is 3 times the x value which means: y=3x
