Answer:

B.64 miles

Step-by-step explanation:

Let Oliver's be x

Let Stephanie's be y

x = 2y -  -  - (a) \\ x + y = 96 -  -  - (b)

substitute for x in (b):

2y + y = 96 \\ 3y = 96 \\ y = 32

find x in (a):

x = (2 \times 32) \\ x = 64

The correct answer is A, 96 divided by 3 is 32 that’s 1/3 of the miles therefore making it so to finish it you need to double the miles.

In a survey of 1046 adults conducted by Bradley Corporation, subjects were asked how often they wash their hands when using a pu
prohojiy [21]

Answer:

Sample = 1046

Population = All adults.

Step-by-step explanation:

In Statistics, a sample can be defined as a set of items, objects or individuals collected, selected or drawn from a population. Thus, a sample is a subset of a population. In this scenario, the sample is 1046.

On the other hand, population can be defined as the total number of individuals in a survey. Thus, all the adults are a population.

Suppose you carry out a significance test of h0: μ = 8 versus ha: μ &gt; 8 based on sample size n = 25 and obtain t = 2. 15. Fin
OLEGan [10]

Using a t-distribution calculator and finding the p-value, the correct option regarding the conclusion is given by:

a) the p-value is 0.02. We reject h0 at the 5% significance level because the p-value 0.02 is less than 0.05.

<h3>What is the relation between the p-value and the conclusion?</h3>

It also involves the significance level, as follows.

  • If the p-value is less than the significance level, we reject the null hypothesis h_0.
  • If it is more, we do not reject.

In this problem, a t-distribution calculator for a right-tailed  with <em>t = 2.15 and 25 - 1 = 24 df</em> is used to find a p-value of 0.02.

It is less than 0.05, hence option a is correct.
