The height of the rose plants in a garden is Normally distributed with a mean 100cms. Given that 10% of the plants have height greater than 104cm. Find (i) The S.D of the distribution (ii) The number of plants have height greater than 105cms if there were 200 plants in the garden.

Is the average time to complete an obstacle course different when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye. Time to Complete the Course Right 40 40 41 43 49 48 45 48 Left 37 36 41 43 48 46 46 43 Assume a Normal distribution. What can be concluded at the the a = 0.05 level of significance level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Họ: pd vV (please enter a decimal) Select an answer v H1: ud vv (Please enter a decimal) Select an answer v b. The test statistic t v- (please show your answer to 3 decimal places.) c. The p-value = (Please show…

King, a golden retriever, can find a tennis ball hidden in his yard 89% of the time, while Tessa, a Labrador mix, can find a tennis ball hidden in her yard 94% of the time. Suppose King’s owner hides a tennis ball in his yard 100 times and Tessa’s owner hides a tennis ball in her yard 150 times. Let K = the proportion of times King finds the tennis ball and T = the proportion of times Tessa finds the tennis ball. What is the probability that the proportion of tennis balls King finds is greater than the proportion Tessa finds? 0.050 0.088 0.476 0.912

If a coin is flipped 225 times and the number of Hs is 75. Compute the proportion of Hs. Round to three places.

Out of 57 high school female athletes, data was collected on how much they were able to bench press. From this data we get x=79.9,Q1=70, Q2=80, and Q3=90. Determine if the data distribution is skewed or symmetric. Give 2 reasons to back up your answer.

As part of a sixth-grade class project the teacher brings to class a jar containing 200 gumballs of two different colors: red and green.  Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar.  Andy draws a sample of 25 gumballs, of which 8 are red and 17 are green.  Use Andy's sample to estimate the number of red gumballs in the jar. There are approximately Answer red gumballs in the jar.
