The ————— that we associate with an interval estimate is called the confidence level.
The higher the probability the ———————— is the confidence.
The most commonly used confidence levels are
The confidence limits are the upper & lower limits of the
We use t- distributions when the sample size is
We use t- distributions when samples are drawn from the —————— population.
For 2 sample values, we have ————— degree of freedom.
For 5 sample values, we have ————— degree of freedom.
The ratio of the no. of elements possessing a characteristic to the total no. of elements in the population is known as
The ratio of the no. of elements possessing a characteristic to the total no. of elements in a sample is known as
The mean of the sampling distribution of sample proportion is ——————— the population proportion.
For ————— samples , the sample proportion is an unbiased estimate of the population proportion.
The finite population correction factors should be used when the population is
Which would you prefer for ——” The universe is large”
Which would you prefer for ——” The Statistical inquiry is in depth”
Which would you prefer for ——” Where testing destroys the quality of the product”
In Hypothesis Testing when H0 is true, it is called
P (type I error) means
The procedures for determining the sample size for estimating a population proportion are similar to those of estimating a population mean. In this case we must know ———— —— facto Rs.
In determining the sample size for estimating a population mean , the no. of factors must be known is
In audit test Statistical Sampling methods are used.
In cost accounting operation Statistical Sampling methods are used.
The difference between the estimate from the sample and the parameter to be estimated is
The estimated true proportion of success is required to determine sample size for
The standard deviation is required to determine sample size for
The desired confidence level is required to determine sample size for
The permissible sampling error is required to determine sample size for
In Control of book keeping and clerical errors Statistical sampling methods are used.
The Exploratory sampling is known as
Single, double, multiple and sequential are several types of
Standard deviation of a sampling distribution is itself the standard error.
Sampling error increases with an increase in the size of the sample.
Deliberate sampling is free from bias.
Which would you prefer ————A higher degree of confidence is desired.
Which would you prefer ———— Previous experience reveals a low rate of error.
Testing the assumption that an assumed population is located at a known level of significance is known as
Purposive selection is resorted to in case of judgment sampling
In test for means of Paired data, if the computed value is _________ than the table value the difference is considered significant.
Cluster sampling is ideal in case the data are widely scattered.
Stratified random sampling is appropriate when the universe is not homogeneous
