Discard Null hypothesis at $alpha=0.05$ but retain at $alpha=0.10$. Discard Null hypothesis at $alpha=0.01$ but retain at $alpha=0.05$. Discard Null hypothesis at $alpha=0.10$ but retain at $alpha=0.05$. Discard Null hypothesis at $alpha=0.10$, $0.05$ and $ 0.01$. Do not Discard Null hypothesis at $alpha=0.10$, $0.05$, or $0.01$. This problem aims to familiarize us with the concept […]

Find the corresponding score for the given observation and select the right one from the given options: a) 0.97 b) -0.97 Read moreLet x represent the difference between the number of heads and the number of tails obtained when a coin is tossed n times. What are the possible values of X?c) 0.64 d) -0.97 […]
The aim of the question is to find the two assumptions which are considered while estimating the cost function. The basic concept behind estimating cost function is cost behavior analysis. Cost behavior analysis identifies the change in the total cost of the product at the end due to the change in its activity level. For […]
The aim of this question is to find the number of observations in the set which are less than its median value of $38$. The concept behind this question is the Locator/ Percentile method. We are going to use the Locator/ Percentile method for finding the number of observations in the given five-number summary. Read […]
The purpose of this question is to find the $p$ value for $H_a$: $p$ > $0.5$ using the z-test statistics test. The $p$-value approach determines the “likely or unlikely” probability, assuming the null hypothesis is true and determining more extreme test statistics in the direction of the alternative hypothesis than the one observed. If the $p$-value […]
