A manufacturer of golf equipment wishes to estimate the number of left-handed golfers. A previous study indicates that the propo

never [62]

Answer:

A sample of 997 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the z-score that has a p-value of $1 - \frac{\alpha}{2}$ .

The margin of error is of:

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

A previous study indicates that the proportion of left-handed golfers is 8%.

This means that $\pi = 0.08$

98% confidence level

So $\alpha = 0.02$ , z is the value of Z that has a p-value of $1 - \frac{0.02}{2} = 0.99$ , so $Z = 2.327$ .

How large a sample is needed in order to be 98% confident that the sample proportion will not differ from the true proportion by more than 2%?

This is n for which M = 0.02. So

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

$0.02 = 2.327\sqrt{\frac{0.08*0.92}{n}}$

$0.02\sqrt{n} = 2.327\sqrt{0.08*0.92}$

$\sqrt{n} = \frac{2.327\sqrt{0.08*0.92}}{0.02}$

$(\sqrt{n})^2 = (\frac{2.327\sqrt{0.08*0.92}}{0.02})^2$

$n = 996.3$

Rounding up:

A sample of 997 is needed.

If the weight of a package is multiplied by 5/7 the result is 40.5 pounds. Find the weight of the package.

ololo11 [35]

Well, it would become 5/7x=40.5. Divide both sides by 5/7, so it is 40.5 * by the reciprocal of 5/7 (7/5). The answer is 56.7 pounds.

An 8-ounce bottle of hand lotion costs $4.72. What is the unit price?

Alik [6]

The answer:

$0.59

Explanation:

The unit rate is the price of each ounce, so you would divide 4.72 by 8 and get 0.59.

Joe wants to buy a skateboard but he doesn't know if he has enough money. THe price of the skateboard is $85 and the sales tax i

koban [17]

Answer: $5.1

Step-by-step explanation:

From the question, we are informed that thee price of the skateboard is $85 and that the sales tax is 6%.

To calculate the sales tax for the skateboard in dollars in cents, we find 6% of$85. This will be:

= 6% of $85

= 6% × $85

= 6/100 × $85

= 0.06 × $85

= $5.1

= 5 dollar, 10 cents
