Question

Transcribed Image Text:Our null hypothesis is that the true coefficient is zero. In
which case would we choose to use a one-sided alternative
hypothesis over a two-sided alternative hypothesis?
We choose a one sided alternative hypothesis when we have a
large sample size.
We choose a one sided alternative hypothesis when we specify a
low (0.01) significance level.
It does not matter what type of alternative hypothesis we specify.
Choose a one sided alternative hypothesis when the theory and
literature suggests either that the true coefficient should be
greater than zero or that the true coefficient should be less than
zero.

- You recently obtained a job with a sports analytics firm, and your first assignment is to write a report evaluating early evidence behind predictions for the 2019-20 NBA season. You will use your knowledge of hypothesis testing to assess the predictions. 1. When conducting a hypothesis test for the population mean, you will not know the population standard deviation, so you will have to use the sample standard deviation instead. How will this affect the process?arrow_forwardHeteroskedasticity can occur in a regression model if (a) the functional form of the regression model is misspecified (b) the Breusch-Pagan test results in a large p-value (c) the White test results in a large p-value (d) the regression model includes too many independent variables (e) the Breusch-Pagan test statistic is smaller than the critical valuearrow_forwardplease quickly thanks !arrow_forward
- In the p-value approach to hypothesis testing, we reject the null hypothesis if O p-value > 0.05 O p-value 0.05 O p-value 0.05 O p-value < 0.05arrow_forwardSuppose we have sample data on (y,x) of size n. Consider regressing y on x and a constant using the least square method (OLS estimation). The estimated equation is y = 2.59 +5.19 x + e where e is the residual. The standard errors for the constant and the coefficient were 0.51 and 1.58 respectively. To test the null hypothesis of zero coefficient (for x) at a given significance level, we may use t-statistic. Compute the t-statistic for the coefficient. Make sure the answer is round up to the nearest hundredth. e.g. 3.015 --> 3.02arrow_forwardSpatial Resolution: Regionally specific fine-scale features and changes are difficult to capture in global climate models since they usually operate at coarse spatial resolutions. The inability to produce precise and comprehensive forecasts for localised consequences is a result of this restriction. Generate a hypothesis related to this problemarrow_forward
