Hello!
So, using simple equation format, an equation could be:
$134.15 + $33.85 = m
Now we have to add the products.
134.15
+ 33.85
__________
168
Originally, Ronald had $168.

Answer:
1. H0: σ2 ≤ 0.0008
Ha: σ2 > 0.0008
2. test statistic = 32.625
3. p value = 0.2931
4. D
Step-by-step explanation:
s² = 0.0009
alpha = 0.05
σ² = 0.0008 this is the value that we would be testing
1. <u>hypothesis</u><u>:</u>
H0: σ2 ≤ 0.0008
Ha: σ2 > 0.0008
2. <u>test </u><u>statistic</u><u>:</u>
X² = (n-1/σ²)s²
= ((30-1)/0.0008)0.0009
= 32.625
3. <u> </u><u>p-value:</u>
P(X² > 32.63) = 0.2931
4. <u>conclusion</u><u>:</u>
the p-value at 0.2931 is greater than alpha at 0.005, (0.2931>0.05). So the correct option is D. we do not reject H0. the sample does not support conclusion that the population variance specification is being violated.
The correct answer for this question would be the last option. The complete factor of 25x^2 – 36 is <span>(5x – 6)(5x + 6). To check, multiply both values. 5x times 5x is 25x^2, and -6 times 6 is -36. Which gives us 25x^2-36. Hope this answers your question. Let me know if you need more help next time.</span>
