A golf association sets performance standards for golf balls. For example, the initial velocity of the ball may not exceed 250

Oksanka [162]

Answer:

In this context 38% represents that if the mean speed of ball is 250 ft/sec, then there is 34% chance of obtaining a similar or more extreme value related to test statistics.

Step-by-step explanation:

We are given that the initial velocity of the ball may not exceed 250 feet per second when measured by an apparatus approved by the association.

Based on the mean speed in the sample, the association comes up with a P-value of 0.38.

Let $\mu$ = <u><em>mean speed of the ball</em></u>

So, Null Hypothesis, $H_0$ : $\mu$ = 250 ft/sec

Alternate Hypothesis, $H_A$ : $\mu$ > 250 ft/sec

Now, the P-value given to us is 0.38.

P-value basically tells us the exact percentage where our test statistics lie. Also, it is the probability of obtaining the value that is more extreme, given that null hypothesis is true,

So, in this context 38% represents that if the mean speed of ball is 250 ft/sec, then there is 34% chance of obtaining a similar or more extreme value related to test statistics.

Over the course of one day, a store owner determined that 80% of customers bought a drink and 30% of customers bought a snack. I

svetoff [14.1K]

Answer:

200

Step-by-step explanation:

Let the total number of customers that day be "x"

30% of total customers bought a snack and that is 120.

So we can say:

30% of total (x) is 120

Note: 30% converted to decimal is 30/100 = 0.3

This can be translated to an algebraic equation as:

0.3x = 120

Now, we can solve for x, the total customers:

0.3x = 120

x = 120/0.3

x = 400

Since, 80% bought drink, we find 80% of 400:

80% = 80/100 = 0.8

0.8 * 400 = 320

The store sold 320 drinks and 120 snacks. So drinks outweigh snacks be:

320 - 120 = 200

So,

200 more drinks than snacks
