ioda

Answer:

Shane had $240 at the beginning of his trip.

Step-by-step explanation:

Shane returned from a trip to Las Vegas with $420 and this is 75% more of at the beginning.

Let us assume the money he carried at the beginning of the trip was $x

At present he is having 75% more means total money he has = x+75% of x

This total amount is equal to $420

Therefore x + .75x = 420

x(1 +.75) =420

1.75 x = 420

Now by dividing both sides by 1.75

x = 420÷1.75

   = $240

Therefore the amount he carried in the beginning of the trip is $240.

Paraphin [41]

Complete Question:

The manager at a sports radio station will be covering several football games over the weekend. She knows that most of her listeners are at least 22 years old and wants to know what age group she should gear her advertisements to for the games. She takes a random sample of 46 listeners from age 22-39 and 57 listeners who are 40 and older and asks them if they are likely to tune in to football games. The "yes" responses are recorded in the file attached below.

1. At the 0.05 level of significance, is there a significant difference in the proportion of listeners based on age?

2. Is there evidence to suggest that there is a significant difference in the proportion of listeners based on age?

Answer:

1) There is no significant difference in the proportion of listeners based on age

2) No, there is no evidence

Step-by-step explanation:

Sample size of group 1, n_1 = 46

Sample size of group 2, n_2 = 57

Number of Yes in group 1,  X_1 = 32

Number of Yes in group 2, X_2 = 47

Proportion of Yes in group 1:

\hat{p_1} = \frac{X_1}{n_1} \\\hat{p_1} = \frac{32}{46}\\\hat{p_1} = 0.6957

Proportion of Yes in group 2:

\hat{p_2} = \frac{X_2}{n_2} \\\hat{p_2} = \frac{47}{57}\\\hat{p_2} = 0.8246

Null Hypothesis, H_0: p_1 = p_2

Alternate Hypothesis,H_a: p_1 \neq p_2

\hat{p} = \frac{X_1 + X_2}{n_1 + n_2}  \\\\\hat{p} = \frac{ 32+47}{46+57} \\\\\hat{p}= 0.767

Significance level,

Calculate the test statistic

z = (\hat{p_1} - \hat{p_2})/\sqrt{(\hat{p} * (1-\hat{p}) * (\frac{1}{N_1}  + \frac{1}{N_2})}\\\\z = (0.6957-0.8246)/ \sqrt{(0.767*(1-0.767)*(1/46 + 1/57))}\\\\z = -1.54

Get the P-value from the probability distribution table:

At z = -1.54, P-value = 0.1236

Since (P-value = 0.1236) > (α = 0.05), we will accept the null hypothesis. This means that there is no evidence to suggest that there is difference in the proportion of listeners based on age.

Two stores offer differently priced sales for the same paper towels, according to the table below. Which store offers the better
blondinia [14]
Answer:
Store 1 has the better deal.

Explanation:
If you divide the amount the prices by the amount of paper towel roll, you would see store 1 has the better deal.

3.60 divided by 12 = 0.30
3.50 divided by 10 = 0.35

As you can see, store 1 is less expensive than store 2. Therefore, store 1 is the better deal.
