We make the claim that the proportion of iphone users to other smart phones is 62%?
We believe the proportion may be higher. We wish to reject Ho if the true proportion is 4% greater than the hypothesized proportion. Use α = 0.02 and β = 0.05 to find the sample size necessary to test this claim.
state the null and alternative hypothesis
draw the curve and label alpha and beta
unstandardize and solve for n
My chance of getting a girlfriend is 4% beat that Android
- Why is the iphone so much better than other smart phones? I'm not trying to start a fight here. It just seems like Apple has access to alien technology or something. I've been trying to help my dad with his Samsung stratosphere and the difference is staggering. Another thing worth noting is that any of my friends who have non iphone smart phones also carry their ipod touches around with them. That says something.
- Recommend newish smart phones no bigger than iPhone 6? I know very little about smartphones and their rankings and such, as I still have the same phone from over 4 years ago. I want nothing bigger than the iPhone 6 as I value how comfy a phone is inside a pocket.
- Is tbere any major différence between thé iPhone 6 and the 6s? Whooppeee is Xmas again and my daughter wants new 2nd hand) iPhone… 2 years ago almost bought her 5 before i réaliséd that it was 5s she wanted ( cos thé 5 sucks?) And I don't want to screw up this year…
- IPhone vs other smart phones? BESIDES THE ORIGINAL COST OF THE IPHONE WHEN BUYING IT, how is the monthly cost of an iPhone any different than the monthly cost of any other smart phone like an android or the galaxy 3S? Cuz so many people are saying iPhones are extremely expensive, and I know the original cost of just buying the iPhone is more expensive than other smart phones, but besides that how is the cost any different from other smart phones?
