In the following you will see 4 survey questions. Answer the following questions about them: Identify what kind of data each of the following survey questions gathers (categorical, ordinal, continuous) and briefly explain your reasoning based on the characteristics of each data type. What methods would you use to summarize this type of data? Methods to choose from are:  count, mode, mean, standard deviation (clearly address which survey question you are answering. for instance, survey question1: , etc)     survey question 1 – on a 7-point scale (1=not satisfied and 7=very satisfied), how do you rate your satisfaction   survey question 2 – How often do you take a trip in your car that’s 100 miles or more?___ less than once month___ 1-2 times a month___ 3-5 times a month___ more than 5 times a month   survey question 3 – What is your auto insurance company? ______________________________ survey question 4 – what is your age? Provide a number.

You are an analyst in a company that sells vacation to young, single people. You want to compare men and women on their preferred vacation destination (beach, mountains, city). 1 – produce the null and alternative hypotheses 2 – Imagine your calculations show there is no associations between gender and preferred destination, but more studies suggest that your conclusion was wrong. In that case, what type of error you have made? Explain your reasoning.

A rate constant obeys the Arrhenius equation, the factor A being 2.2 ×10 13 s –1 and the activation energy being 150. kJ mol –1. What is the value of the rate constant at 227°C, in s –1?

In an exothermic reaction,

Safrole is used as a topical antiseptic. Calculate the vapor pressure of a solution prepared by dissolving 0.75 mol of safrole in 950 g of ethanol ( M = 46.07 g/mol).  P° ethanol = 50.0 torr at 25°C.

If a solute dissolves in an endothermic process

A boiled egg can be cooked at 100.0°C in exactly 5 minutes. At an altitude of around 2000 m where the boiling point of water is 93.0°C, it takes exactly 7.5 minutes to cook the egg to the same amount. What is the activation energy for the reaction involved when an egg is boiled?
