You measure 33 backpacks' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 12
saul85 [17]

Answer:

E=3.4363

Step-by-step explanation:

#Given a significance level of \alpha=1-CI=1-0.90=0.1 and

\bar x=36, \ \sigma=12.1 \ n=41, the critical value is,z_\alpha_/_2=z_\alpha_/_0_._0_5=1.645

#the margin of error can then be calculated as:

E=z_\alpha_/_2\times\frac{\sigma}{\sqrt n}=1.645\times \frac{12.1}{\sqrt 33}\\\approx 3.4363

Hence the margin of error is 3.4363

Which phone has a better price plan: IPhone 11 Pro or Samsung Galaxy S10? Why? What are the price plans? Brainliest for the best
jok3333 [9.3K]

Answer:

Samsung S10

Step-by-step explanation:

        Price Plans

iPhone 11 Pro: $41.67/mo.

Galaxy S10: $31.25/Mo

<u>_________________</u>

         Why?

<em>The Galaxy S10 has a 6.1-inch screen that's slightly larger than the iPhone 11 Pro's 5.8-inch display. It's also sharper than Apple's iPhone, or at least it should be on paper. ... But having a higher resolution doesn't always mean one screen is better than the other.</em>
