Answer:
Step-by-step explanation:
From the information given, we would write the hypothesis.
For the null hypothesis,
H0 : µ = 70
For the null hypothesis,
Ha : µ > 70
This is a right tailed test because of the symbol of greater than.
The decision rule is to reject the null hypothesis if the level of significance is greater than the p value and accept the null hypothesis if the level of significance is lesser than the p value.
Therefore, since the significance level, 0.05 > p value, 0.01635, then we would reject the null hypothesis. There is enough evidence that the mean speed of all cars is greater than the posted speed limit of 70 mph.
<h2> Heya </h2>
<h3>Selling Price = Rs. 851</h3>
<h3>Loss = 8%</h3>
<h3>FORMULA = 100/100 - LOSS % × SP</h3>
<h3>CP = 100/100 - 8 × 851</h3>
<h3> CP = 100/92 × 851</h3>
<h3> CP = Rs. 925</h3>

Answer:
710%
Step-by-step explanation:
Find each unit price.
16.20 $/bucket × (1 bucket / 450 eggs) = 0.036 $/egg
3.50 $/dozen × (1 dozen / 12 eggs) = 0.292 $/egg
The percent markup is:
(0.292 − 0.036) / 0.036 × 100% ≈ 710%
The store marks up the price by approximately 710%.
