WORK MUST BE SHOWN ON THIS QUESTION TO RECEIVE CREDIT. Use the given information to find the P-value.  Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a right-tailed test is z=0.52. The p-value is . (Round to three decimal places as needed.) State the correct conclusion about the null hypothesis.

The data represents the heights of eruptions by a geyser. Height of eruption (in.) 65 32 50 90   80 50 40 70 50 61 78 53 59 65 69 60 78 70 40 86 Use the heights to construct a stemplot. 

Refer to the accompanying data display that results from a simple random sample of times (minutes) between eruptions of the Old Faithful geyser.  The confidence level of 95% was used.  T Interval (63.97, 72.55) = 68.26 Sx = 12.11 n = 33 (a) Express the confidence interval in the format that uses the “less than” symbol.  Round the confidence interval limits given that the original times are all rounded to one decimal place. min < < min (Round to two decimal places as needed.) (b) Identify the best point estimate of and the margin of error. The point estimate of is minutes. (Round to two decimal places as needed.) The margin of error E = minutes.  (Round to two decimal places as needed.) Formulas and Tables-79486924-005c-414a-b0f6-991d200540a1.pdf

Forty different video games showing drug use were observed.  The duration times of drug use (in seconds) were recorded.  When using this sample for a t-test of the claim that the population mean is greater than 88 seconds, (a) What does df denote? Enter your choice from the options below.  A. The test statistic B. The number of degrees of freedom C. The sample standard deviation D. the sample size (b) The value of df is . (Type an integer or a decimal.  Do not round.) Formulas and Tables-d934df24-8602-4dd0-b92f-5c68bee9b9df.pdf

WORK MUST BE SHOWN. An IQ test is designed so that the mean is 100 and the standard deviation is 10 for the population of normal adults.  Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 95% confidence that the sample mean is within 5 IQ points of the true mean.  Assume that =10 and determine the required sample size.  Then determine if this is a reasonable sample size for a real world calculation. The required sample size is .  (Round up to the nearest integer.) Would it be reasonable to sample this number of students? Explain.  Formulas and Tables-78c00ed4-9838-46f4-b814-a717e18bec43.pdf

Identify which of these types of sampling is​ used: random,​ systematic, convenience,​ stratified, or cluster. To determine her body temperature​, Jean divides up her day into three​ parts: morning,​ afternoon, and evening. She then measures her body temperature at 2 randomly selected times during each part of the day.

A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie.  Among the 500 respondents, 11% chose chocolate pie, and the margin of error was given as 5 percentage points.  Given specific sample data, which confidence interval is wider, the 95% confidence interval or the 80% confidence interval?  Why is it wider?

Prokaryotes lack a nucleus and complex organelles, allowing for a simpler and faster replication process known as binary fission.

Crossing two heterozygous parent organisms will always result in a 2:2 inheritance pattern.
