Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write wit
SCORPION-xisa [38]

Answer:

Type I error is to Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29.

Type II error is Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is different from 0.29.

Step-by-step explanation:

We are given the following hypothesis below;

Let p = <u><em>proportion of people who write with their left hand</em></u>

So, Null Hypothesis, H_0 : p = 0.22     {means that the proportion of people who write with their left hand is equal to 0.22}

Alternate Hypothesis, H_A : p \neq 0.22      {means that the proportion of people who write with their left hand is different from 0.22}

Now, Type I error states that we conclude that the null hypothesis is rejected when in fact the null hypothesis was actually true. Or in other words, it is the probability of rejecting a true hypothesis.

So, in our question; Type I error is to Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29.

Type II error states that we conclude that the null hypothesis is accepted when in fact the null hypothesis was actually false. Or in other words, it is the probability of accepting a false hypothesis.

So, in our question; Type II error is Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is different from 0.29.

250% increase of 28,000?
Phoenix [80]
250% can be converted into a fraction 250/100 or into a decimal 2.50.
 so  250% of 28,000 is 2.50 times 28,000 which is 70,000.
28,000 is increased by 70,000 to 98,000

A specific cars engine has a capacity of 5.1 Lof oil. How many quarts of oil does the engine have?
mr Goodwill [35]

<u>ANSWER: </u>

The engine have 5.39 qt approximately.

<u>SOLUTION: </u>

Given, a specific cars engine has a capacity of 5.1 L of oil.  

We need to find how many quarts of oil does the engine have?

Number of quarts of oil is product of number of liters of oil and the number of quarts per liter.

We know that, one liter of liquid contains 1.056 quarts approximately.

Number of quarts of oil = number of liters of oil x number of quarts per liter.

Number of quarts of oil = 5.1 liters x 1.056 quarts.

Number of quarts of oil = 5.1 x 1.056  

Number of quarts of oil = 5.389 qt.

Hence, the engine have 5.39 qt approximately
