A randomly selected group of 100 men and women was studied to see whether there was any difference between the sexes in the incidence of hayfever. Of the 54 men in the sample, 11 reported that they suffered from hayfever. Of the women, only 4 suffered from hayfever. Use a χ2 test to determine whether the incidence of hayfever differs between the sexes. What is the value of χ2 and what is the probability P (two-tailed) that the apparent association could have arise by chance?     χ2 = 1.29, P = 0.243     χ2 = 1.02, P = 0.339     χ2 = 1.87, P = 0.164     χ2 = 2.66, P = 0.103 how do i perform this on prism?

true or false - It is given that a random variable X follows normal distribution with meanσ=20andstandarddeviationμ=3. ThenP(14≤X≤26)<0.9.

I have purchased a machine worth P1,732,173.00. And it needs maintenance every 6 months starting from its purchased date for the first 10 years of its useful life. The maintenance cost is equivalent to the 2% of the total machine cost. How much money should be prepare today to finance the requirement if the interest rate is 0.10 compounded quarterly? with format: GIVEN: REQUIRED: SOLUTION:

If we want to import a categorical variable with 5 different categories in a linear regression, we need to generate how many dummy variables?

Task B4.2  Since the iceberg is melting over time during the journey, the next level of complexity is to include the time-dependence of the iceberg’s speed if the tug pulls at constant power.  (a) Write down the iceberg radius as a function of time, and then the pulling speed as a function of time.  (b) How are the total journey time, journey length and the time-dependent speed related? Derive an expression for the final iceberg radius as a function of initial iceberg radius. (Hint: the final radius is related to initial radius and the journey time).  (c) Now you know how the final radius depends on initial radius, you can calculate the income from selling the delivered iceberg and the fuel costs of the tug. Develop a Matlab script to plot the gross profit (sales minus fuel costs) as a function of initial iceberg size.  (d) Use your Matlab work to find the following: i. The minimum initial iceberg size for the sales revenue to be greater than the given fuel costs (positive gross profit); ii. The initial iceberg radius and associated gross profit if the total journey time is limited to 30 days due to seasonal factors; iii. What these will be if the fuel price increases to 140p per litre.
