13. Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (u, P, o) for the indica
liraira [26]

Answer:

Null Hypothesis, H_0 : P = 4.1%

Alternate Hypothesis, H_A : P > 4.1%

Step-by-step explanation:

We are given that a psychologist claims that more than 4.1% of the population suffers from professional problems due to extreme shyness.

<u><em>Let p = true percentage  of the population that suffers from extreme shyness.</em></u>

So, Null Hypothesis, H_0 : P = 4.1%

Alternate Hypothesis, H_A : P > 4.1%

Here, <em><u>null hypothesis states that</u></em> % of the population who suffers from professional problems due to extreme shyness is equal to 4.1%.

On the other hand, <u><em>alternate hypothesis states that</em></u> more than 4.1% of the population suffers from professional problems due to extreme shyness.

So, the above hypothesis would be appropriate for conducting the test.

Javier had $305 in his bank account. His bank charges a monthly fee of $7.50.
EastWind [94]

Answer:

$282.50

Step-by-step explanation:

He will be charged $7.50 for 3 months, which is a total of 7.5 * 3 = $22.50.

Subtract this from the amount in his account to find the amount of money he has at the end of the three months:

305 - 22.5 = 282.5

The answer is therefore $282.50.

layla earned $42.00 babysitting in two days. She worked 2.25 hours yesterday and 3.25 hours today. If layla was paid the same am
algol [13]
Well if she earned the same amount per hour the hours can be added. 2.25 + 3.25 = 5.5 hours. To get the rate of earning per hour you would then divide the total made by the total time worked. 42/5.5 = $7.64 approximately.
