In a recent poll, style="color: rgb(0,0,0); "> 822 adults were asked to identify their favorite seat when they fly, and 518
of them chose a window seat. use a 0.05
0.05 significance level to test the claim that the majority of adults prefer window seats when they fly. identify the null hypothesis, alternative hypothesis, test statistic, p-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. use the p-value method and the normal distribution as an approximation to the binomial distribution.
which of the following is the hypothesis test to be conducted? i also needed the test statistic for z and the p value
a.
upper h 0 : p not equals 0.5
h0: p≠0.5
upper h 1 : p equals 0.5
h1: p=0.5
b.
upper h 0 : p equals 0.5
h0: p=0.5
upper h 1 : p greater than 0.5
h1: p> 0.5
c.
upper h 0 : p greater than 0.5
h0: p> 0.5
upper h 1 : p equals 0.5
h1: p=0.5
d.
upper h 0 : p equals 0.5
h0: p=0.5
upper h 1 : p less than 0.5
h1: p< 0.5
e.
upper h 0 : p equals 0.5
h0: p=0.5
upper h 1 : p not equals 0.5
h1: p≠0.5
f.
upper h 0 : p less than 0.5
h0: p< 0.5

Activity two: just lemons, inc. production here's a one-batch sample of just lemons lemonade production. determine the percent yield and amount of leftover ingredients for lemonade production and place your answers in the data chart. hint: complete stoichiometry calculations for each ingredient to determine the theoretical yield. complete a limiting reactant-to-excess reactant calculation for both excess ingredients. water sugar lemon juice lemonade percent yield leftover ingredients 946.36 g 196.86 g 193.37 g 2050.25 g 89% just lemons lemonade recipe equation: 2 water + sugar + lemon juice = 4 lemonade mole conversion factors: 1 mole of water = 1 cup = 236.59 g 1 mole of sugar = 1 cup = 225 g 1 mole of lemon juice = 1 cup = 257.83 g 1 mole of lemonade = 1 cup = 719.42 g show your calculations below. analysis questions 1. based on taste observations only, which ingredients were in excess in the lemonade samples in activity one? in activity one the excess substances for each sample were the water and sugar. 2. based on the data in activity two, which excess ingredients are affecting the taste of the lemonade in the sample batch? 3. what can just lemons, inc. do during production to reduce the amount of excess ingredients and improve the taste of their lemonade? 4. try to reduce the amount of leftover ingredients by changing the amount of one, two, or all three starting ingredients. show your stoichiometric calculations below. 5. during factory inspection, just lemons, inc. discovered that a water valve to the lemonade mixing station was not functioning. once they repair it, more water will enter the mixing station. from what you know about the limiting and excess ingredients for current lemonade production, what advice would you give engineers about the upcoming increase in water?
