The average weight of a male labrador retriever is believed to be well-approximated by a normal distribution with mean 71.5 lbs

Oliga [24]

Answer: We will reject the null hypothesis.

Step-by-step explanation:

Since we have given that

Mean μ = 71.5 lbs

Standard deviation σ = 7.5 lbs

So, the hypothesis are given below:

$H_0:\mu =71.5\\\\H_1:\mu \neq 71.5$

Since α = 5% level of significance = 0.05

So, there is two tail test.

Critical values of z are 1.96 and -1.96.

So, we will reject H₀ if z<-1.96 or z>1.96

So, first we will find the value of z.

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\\\x=\dfrac{80-71.5}{\dfrac{7.5}{\sqrt{15}}}\\\\\\z=4.39$

According to test statistic approach:

Since z >1.96

as 4.39>1.96

So, we will reject the null hypothesis.

Lois and Clark own a company that sells wagons. The amount they pay each of their sales employees (in dollars) is given by the e

liberstina [14]

Answer:

<h2><u>The amount paid to an employee was </u><u>162</u></h2>

Step-by-step explanation:

<h2><u>The expression 12h + 30w Identifies the amount paid to an employee.</u></h2><h2><u>Let h represent hours and let w represent the total amount of g-wagons sold. </u></h2><h2><u>Since the question explains that an employee works 6 hours and sells 3 wagons, put h as h = 6 and w as w = 3. We would end up getting this equation. 12h + 30w = 12(6) + 30(3).</u></h2><h2><u>Now all you need to do is solve it.</u></h2><h2><u>left side = 72</u></h2><h2><u>right side = 90</u></h2><h2><u>72 + 90 =</u><u> 162</u></h2>

What is 7 2/6 plus 8 5/6

yulyashka [42]

7 2/6 + 8 5/6
= (7 x 6 + 2)/6 + (8 x 6 + 5)/6
= (42 + 2)/6 + (48 + 5)/6
= 44/6 + 53/6
= (44 + 53)/6
= 97/6
= 16 1/6
